(Set Analog Input Sel. in calibration when you use it by current input.) *3,4 F377A and the device connected should be grounded when you use them. (Usually, one side of shield wire should be connected to avoid the cause of faulty operation by forming ground loop. However, when high frequency noise affects the operation, it will be improved by connecting both sides of the shield wire.) *5 Usually, there is no need to wire A. GND, but it causes the fluctuation of the indicated value when the potential difference between A. GND terminal and A. GND terminal of the device connected is produced. In this case, the symptom may be improved by connecting A. GND to AGND of the device connected. *6 F377A is a high resolution type indicator which can perform A/D conversion at supperhigh speed. The wiring between F377A and device connected should be in the short distance to eliminate the effects of induction noise. Moreover, the connection should be apart from AC power source and wiring of large volume current. Conduct adequate checking before the operation. 20

22 2 INSTALLATI & CNECTI SI/F connection The 2-wire serial interface has connective ability for coupling a UNIPULSE printer, external display, etc. Connect from A11 and A12 of the external input/output connector. The interface is nonpolarized and up to three external instruments may be connected.

Work Setting Hold Setting Page 1 Hold setting --- Inflection point --- If you select the inflection point hold in the hold function setting, set the inflection point detection parameters "inflection minimum slope", "inflection front sope time" and "inflection rear sope time". Set referring to the principle of operation only when the value cannot be held successfully with the factory settings or when further adjustments are required. 5 SETTING OF FUNCTIS Detection of the inflection point The logic of detecting the inflection point is given below. Assuming that the remainder obtained by subtracting the amount of change C of the indicated value over A from the amount of change of the indicated value over B is D, when the amount of change D exceeds the inflection minimum slope, point a is held as an inflection point. If there are two or more inflection points in the hold section, the point having a larger change is held. The inflection point is normally detected by A=B, but it may easily be detected with A<B where the slope is gradual. Inflection point Held as an inflection point if D > inflection judgment value.

Work Setting Hold Setting Page 2 48

50 5 SETTING OF FUNCTIS Inflection front (rear) slope time setting is the number of samplings. Since the F377A's sampling speed is 2000 times/sec., one sampling is 0.5msec. Therefore, setting of the interval at 100 means setting of 50msec. Caution regarding inflection point hold Load change time Inflection True inflection point point If the detection Inflection front sope time and Inflection rear sope time are set too short, fine load changes may be detected as shown in the illustration on the left-hand side, so that a correct value cannot be held. In this case, set the detection inflection rear sope time large enough to bring it as close to the load change time as possible, and also set the inflection minimum slope large according to the amount of change at that time, so that the inflection point is held at a correct position. Example of inflection point hold setting Example of ideal waveform setting Set the load change time (between the inflection point and when the change stops) to inflection rear sope time. In the example, it is set to 200 since it is 100 msec. Set the same value as inflection rear sope time to inflection front sope time. Set load D obtained by subtracting load C changing with inflection front sope time from the load changing with inflection rear sope time to the inflection minimum slope. In the example, set load change D=80 obtained by subtracting load C=10 changing with A from load 90 changing with B to the inflection minimum slope. However, since an inflection point is not judged until load change D exceeds the inflection minimum slope, actually set the inflection minimum slope a slightly smaller than D. If the inflection point cannot be located successfully 1 When holding above the inflection point and moving downward 1 1) It is considered that the inflection minimum slope is small with respect to load change D. Set the inflection minimum slope larger. 2) If lowering is insufficient in 1), increase inflection front sope time msec A 100msec B 2 D = 80 C = 10 When holding below the inflection point and moving upward inflection rear sope time is too long and the inflection minimum slope is too large.shorten inflection rear sope time and decrease the inflection minimum slope.

Then, if the average sample number is set at 2 or more, the representative value of the sampling values by the set number (average by the number) is adopted as the sampling data used for average calculation. The maximum average value detection time with the setting 1 is 5 sec., but the average value detection time can be extended by this setting. Maximum average value detection time=average sample number 5 [sec.] where the number of updates of the average value will decrease.

(Example) All section peak hold T/H + HOLD Button HI-LO Limit Judging Output H/E HOLD PEAK* External signal Sensor Input Value t1 Detection Hold Section Undetermind section (Note) Blink t1: A delay time between the instant when the T/H signal is inputted and the instant when the indicated value is held 1.0ms (max.) t2: A delay time between the instant when the T/H signal is released and the instant when the indicated value returns to tracking 1.0ms (max.) t3: A minimum reset signal width required for releasing the hold 1.0ms (min.) Note: During the undetermined section, the judging output varies with fluctuations in the input waveform. However, the H/E output remains on during the undetermined section. Read the judging result when the indicated value becomes stable (immediately before the T/H signal rises). By this method, the hold detection section is externally specified by the SECTI signal to maintain the hold value until the reset signal is turned on.the hold is released by turning on the T/H signal as a reset signal.the next detection is started when the SECTI signal is turned on again even if the T/H signal is not turned on. The H/E output signal is on between the instant when the SECTI signal is turned off and the instant when the T/H signal is turned on. (Example) Externally specified section peak hold t2 t3 *The status display changes depending on the hold mode. + Indicated Value t1 Detection Hold Section Undetermind section (Note) Blink t2 t3 Indicated Value Sensor Input Value t t1: A delay time between the instant when the SECTI signal is inputted and the instant when the value to be held is detected 1.0ms (max.)

56 5 SETTING OF FUNCTIS External signal + time Hold is detected during the predetermined time (hold section time) from the point in time when the SECTI signal is turned on. The hold is released by turning on the T/H signal as a reset signal.the next detection is started when the SECTI signal is turned on again even if the T/H signal is not turned on. The H/E output signal is on between the instant when the SECTI signal is turned off and the instant when the T/H signal is turned on.

Hold is detected during the predetermined time (hold section time) from the point in time when the indicated value crosses the hold start level. The hold is released by turning on the T/H signal as a reset signal. The H/E output signal is on between the instant when the hold section time ends and the instant when the T/H signal is turned on. (Example) Level + Time specified section peak hold + t1: A delay time between the instant Sensor Input Value Indicated when the indicated value exceeds the Value hold start level and the instant when the value to be held is detected Hold Start Level 0.5ms (max.)

57 5 SETTING OF FUNCTIS Level (only Peak and Valley) By this method, the hold detection section is from the point in time when the indicated value crosses the Hold Start Level until it crosses the Hold Stop Level. The hold is released by turning on the T/H signal as a reset signal. The H/E output signal is on between the instant when the hold section time ends and the instant when the T/H signal is turned on. However, there are limitations that the Hold Start Level should be passed HI and the Hold Stop level be passed LO in peak hold, while the Hold Start Level should be passed LO and the Hold Stop level be passed HI in valley hold. (Example) Level specified section peak hold + Sensor Input Value Indicated Value t3: A minimum reset signal width required for releasing the hold 1.0ms (min.) passed HI 5 SETTING OF FUNCTIS Hold Start Level Hold Stop Level T/H H/E HOLD PEAK* HI-LO Limit Judging Output Detection 5-12.Multi-hold Function Blink passed LO Hold Section *The status display changes depending on the hold mode.

86 8 SUPPLEMENTS 8 SUPPLEMENTS 8-1. Error Display List When either of the following errors occur, the RUN signal of an external output is turned off. Sensor +error or Sensor -error This message indicates that the inputted electric signal exceeds the input voltage range of the element (ADC) which converts the inputted electric signal to a digital value whereby the signal cannot be converted to a correct digital value. Sensor +error and Sensor -error indicate that the inputted electric signal exceeds the input range in the positive direction and negative direction, respectively. This message may also be displayed when an excessive load is applied to the sensor or the input terminals are opened due to a break in the cable. +Over or -Over (Overflow error) This message indicates that the value to be displayed except the decimal point and sign exceeds five digits. The message and a value of as much as five digits appear alternately. +OVER and -OVER indicate that the value to be displayed exceeds five digits in the positive direction and negative direction, respectively. This message is displayed in such a case wherein a load larger than expected is applied or calibration is performed below the measuring range. Check calibration and the measuring object. Overload (Overload error) An Overload error results when the real time value (sensor input value) exceeds the alarm HI limit or drops below the alarm LO limit. Check the sensor for excessive load. Zero error (Zero calibration error) This message indicates that calibration cannot be performed because the inputted electric signal exceeds the input voltage range. Check the cables for breaks or miswiring. Span error (Span calibration error) The span calibration error occurs under the following conditions. 1) An actual load set value of zero is inputted. 2) An electric signal of -0.1~0.1V or -0.2~0.2mA with the difference from zero calibration point is inputted. In the case of 1), check the set value, and perform calibration again. In the case of 2), check that the actual load is properly applied and check the cables for miswiring.if the load is too light, the load needs to be increased. Although the F377A will not break down immediately even if the above messages are displayed, Sensor +error or Sensor -error indicates that an excessive voltage may be applied to the input circuit of the F377A. It is therefore required to remove the cause immediately. (Although the input is provided with a protection circuit, a long-time excessive voltage or an instantaneous but extremely high voltage may break the F377A.) Zero limit (Digital zero limit error) A zero limit error results when the range of zero-point correction (deviation from the zero calibration registered point) by digital zero or zero tracking exceeds the Digital Zero Limit set value. Reset the digital zero, or perform digital zero in an appropriate range. 8 SUPPLEMENTS 85
