The MAX MIN Record mode captures minimum, and maximum input
values.
When the input goes below the recorded minimum value or above the
recorded maximum value, the Meter beeps and records the new value.
This mode is for capturing intermittent readings, recording minimum
and maximum readings unattended, or recording readings while
equipment operation precludes watching the Meter.
To activate the MAX MIN mode, press soft key labeled . If the Meter
