7.HOLD FUNCTIONS 7. HOLD FUNCTIONS By the hold function including sample hold, peak hold, valley hold, peak-to-peak hold, relative maximum and minimum hold and inflection point hold, a specific point in a waveform is taken out for HI-LO limit comparison. The operation of each hold will be described in detail. 7-1. Hold Setting --- common --- 7-1-1. Hold Mode The F371 includes nine hold modes as shown in the table below. In the peak, valley, peak-to-peak and mean value modes, period setting is required.
PAGE 59
7.HOLD FUNCTIONS Simple setting call Press the MODE button at the bottom of the indicated value display screen to go direct to the hold mode entry screen. 7-1-2. Hold Detection Time If you set the hold period setting in the hold function setting to Time or Time with Trigger, set the time. Setting range: 0.001 - 9.999 sec.
PAGE 60
7.HOLD FUNCTIONS 7-1-3. Auto Start Level If you select the time specified period mode with trigger, or relative maximum, relative minimum or inflection point hold in the hold mode setting, set the start level. Setting range: -99999 - 99999 How to set Setting call Hold Page 1 In each hold mode of relative maximum/relative minimum/inflection point, if the auto start level is set at 99999, the hold operation starts only with the period signal H/M without performing level detection. 7-1-4.
PAGE 61
7.HOLD FUNCTIONS 7-2. Hold Setting --- relative maximum and relative minimum --If you select the relative maximum and relative minimum hold in the hold function setting, set the relative maximum and relative minimum value detection parameters "minimum count" and "valley detection level". 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.

7.HOLD FUNCTIONS 7-2-1. Minimum Count Setting range: 0001 - 9999 How to set Setting call Hold Page 1 7-2-2. Valley Detection Level Level: 1/4, 1/2, 3/4, 1, 1.25, 1.
PAGE 63
7.HOLD FUNCTIONS 7-3. Hold Setting --- inflection point --If you select the inflection point hold in the hold function setting, set the inflection point detection parameters "minimum slope", "interval A" and "interval B". 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. Detection of the inflection point The logic of detecting the inflection point is given below.
PAGE 64
7.HOLD FUNCTIONS 7-3-1. Minimum Slope Setting range: 00001 - 99999 How to set Setting call Page 2 Hold 7-3-2. Interval A and Interval B Setting range: - Interval A+Interval B - 10 Interval A(B) 1000 990 How to set Setting call Hold Page 2 The interval setting is the number of samplings. Since the F371's sampling speed is 2000 times/sec., one sampling is 0.5msec. Therefore, setting of the interval at 100 means setting of 50msec.
PAGE 65
7.HOLD FUNCTIONS Example of inflection point hold setting Example of ideal waveform setting 100 D = 80 20 10 C = 10 0 100msec A 100msec B Set the load change time (between the inflection point and when the change stops) to interval B. In the example, it is set to 200 since it is 100 msec. Set the same value as interval B to interval A. Set load D obtained by subtracting load C changing with interval A from the load changing with interval B to the inflection point judgment value.
PAGE 66
7.HOLD FUNCTIONS 7-4. Hold Setting --- mean value --- 7-4-1. Mean Value Sampling Count If the mean value sampling count is set at 2 or more in the mean value hold, the representative value of the sampling values by the set count (mean value by the count) is adopted as the sampling data used for mean value calculation. The maximum mean value detection time with the setting “1” is 5 sec., but the mean value detection time can be extended by this setting.
PAGE 67
7.HOLD FUNCTIONS 7-5. Hold Operation 7-5-1. Sample Hold When the T/H signal is inputted, a desired point is held, and the H/E output is turned on. Hold of the value continues as long as the T/H signal is on.
PAGE 68
7.HOLD FUNCTIONS 7-5-2. Peak Hold The maximum value (peak) in the positive direction of the specified period is held. The period is specified by the setting of “all period”, “external signal”, “time”, or “time with trigger”.
PAGE 69
7.HOLD FUNCTIONS 7-5-3. Valley Hold The maximum value (valley) in the negative direction of the specified period is held. The period is specified by the setting of “all period”, “external signal”, “time”, or “time with trigger”.
PAGE 70
7.HOLD FUNCTIONS 7-5-4. Peak-to-Peak (P-P) Hold The maximum value of the difference between the peak and valley over the specified period is held. The period is specified by the setting of “all period”, “external signal”, “time”, or “time with trigger”.
PAGE 71
7.HOLD FUNCTIONS 7-5-5. Relative Maximum and Relative Minimum Hold Detection starts when the indicated value crosses the auto start level with the H/M signal inputted. Detection is performed as long as the H/M signal is on. 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 starts and the instant when the T/H signal is turned on. If the auto start level is not needed as a starting condition of the detection period, set 99999.
PAGE 72
7.HOLD FUNCTIONS The Hold Function in General The delay times of the judging signal and the H/E signal do not include a delay time of the analog circuit (low-pass filter). Also, the delay times are calculated without the digital filter. Since the judging signal and the H/E signal are generated for the value produced through the analog and digital filters, transmission of the signals becomes slower and the delay of each output signal increases with enhancement of the filters.

7.HOLD FUNCTIONS 7-5-6. Inflection Point Hold Detection starts when the indicated value crosses the auto start level with the H/M signal inputted. Detection is performed as long as the H/M signal is on. 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 starts and the instant when the T/H signal is turned on. If the auto start level is not needed as a starting condition of the detection period, set 99999.
PAGE 74
7.HOLD FUNCTIONS 7-5-7. Mean Value Hold The mean value of the sampling values over the specified period is calculated and updated to perform comparison operation. The period is specified by the setting of “all period”, “external signal”, “time”, or “time with trigger”.
PAGE 75
7.HOLD FUNCTIONS 7-6. How to Specify the Hold Detection Period 7-6-1. All Period By this method, the hold detection period is externally specified by the T/H signal. Detection starts with the T/H signal ON to perform each hold operation. Detection ends with the T/H signal OFF to reset the hold.
PAGE 76
7.HOLD FUNCTIONS 7-6-2. Externally Specified Period Hold (Peak, Valley , Peak-to-Peak and Mean Value) By this method, the hold detection period is externally specified by the H/M 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 H/E output signal is on between the instant when the H/M signal is turned off and the instant when the T/H signal is turned on.
PAGE 77
7.HOLD FUNCTIONS 7-6-3. Time Specified Period Hold (Peak, Valley, Peak-to-Peak and Mean Value) Hold is detected during the predetermined time (hold detection time) from the point in time when the H/M signal is turned on. 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 H/M signal is turned off and the instant when the T/H signal is turned on.
PAGE 78
7.HOLD FUNCTIONS 7-6-4. Time Specified Period Hold with Trigger (Peak, Valley, Peak-to-Peak and Mean Value) Hold is detected during the predetermined time (hold detection time) from the point in time when the indicated value crosses the auto 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 detection time ends and the instant when the T/H signal is turned on.
