The decimal point at the right of the display will be lit steadily.
Press again to monitor the peak low value. The decimal point at the right of the display will now
blink on and off.
Press to redisplay the measured value (normal operating mode).

+
FUNC
to reset the peak high/peak low values and to restart for a new peak
detection.
2. Hold-On Value
The external contact can be used to freeze input signal sampling, holding the last measured

flashes on the display.
