Peak hold [PEAK]
Measures the maximum value in the time period (sampling time) specified by the external TIMING input to
display/output it.
• Bottom hold [BOTTOM] ...................Measures the minimum value in the specified time period (sampling time).
• Peak-to-peak hold [P-P] ..................Measures the differential between the maximum and minimum values in
the specified time period (sampling time).
• Average hold [AVG.H].....................Measures the average value in the specified time period (sampling time).
• The sampling time is the time period in which the TIMING input is OFF. The maximum value in the sampling
time right before the TIMING input becomes ON is output.
• In the following cases, the judgment standby status ("- - - -" is indicated) is displayed until the first measured
value is fixed.
When you turn on the power, change the settings, change the program No., input RESE, and input Auto-zero.
• Judgment outputs are output according to the measured value.
• The ON status of each output means that the NPN open-collector output is ON.
• The ON status of each input means that the input and the COM terminal are short-circuited.
• The RS-232C output is synchronized with the timing input when the "D-MODE" in the environment setting is set
to any option other than OFF. ( Page 8-17)
• Refer to "Binary Output" ( page 7-10) for details of the binary output.
• If the TIMING input becomes ON during the reset processing is in progress, the judgment standby status
("- - - -" is indicated) is displayed.
• The TIMING input and RESET input can be controlled using the RS-232C. ( Page 8-6)
• The TIMING input and the RESET input can be controlled by using the [HOLD] button and the [ESCAPE]
button respectively. ( Page 5-3)
Select 2 for the number of times for averaging if the measurement mode is set to average hold.
