Peak Hold Function
Operation in the peak hold state
• Peak hold operation also applies to the following measured values:
(1) Measured values to be stored onto the USB ash drive
(2) Measured values to be acquired using communications
(3) Measured values to be outputted as an analog signal
• Waveforms, the clock, and the peak-over display are refreshed.
• When the display is overloaded, it will show [------]. In this case, cancel the peak hold operation,
then switch the present range over to a range in which the overload condition will not occur.
• The maximum value is determined using the absolute value of measured values. (However, this
method does not aect voltage or current peak values.)
• For example, if a power of −60 W is inputted after that of 50 W was inputted, the display will
indicate [−60 W] because the absolute value of −60 W is greater than that of 50 W.
• When the HOLD key is pressed, the peak hold value is reset, and another peak hold operation
starts from that point.
• The instrument retains the peak-hold value without updating it even if the interval time set in the
time control function has elapsed.
• During average calculation, peak hold operation applies to measured values after averaging.
• Settings that aect measured values such as range and the LPF settings cannot be changed.
• When the range setting is set to [AUTO], the range is xed to that at the time when the
PEAK HOLD key was pressed.
• The hold function cannot be used together with the peak hold function.
• Waveforms shown on the screen and D/A output waveforms are not aected by the peak hold
operation.
• The time when the maximum value occurred is not displayed.
• The peak hold function does not aect to integrated values.
