Auto-Power OFF Feature
The auto power off feature automatically shuts the meter off 12 minutes after the
most recent button press.
Disabling the Auto-Power OFF Feature
With the unit ON, momentarily press the CAL/RECALL key, then quickly press
and hold both the MODE/HOLD and ON/OFF key until ‘oFF’ is displayed. To
restore the Auto Power Off Feature (auto power OFF enable) simply turn the
meter off and on again using the ON/OFF key.
Low Battery Indication
When the battery voltage falls below the operating threshold, ‘BAT’ will
appear on the display. Refer to the Maintenance section for battery replacement
information.
Storing Readings
Up to 25 readings can be stored in memory for later recall.
1. With the meter in the HOLD mode, press and hold the MODE/HOLD key
for 3 seconds to store a reading. Release the key when the memory location
number appears on the lower display.
2. After approximately 30 seconds (measurement duration) the meter will
return to the HOLD mode and another reading can then be stored.
3. If more than 25 readings are stored, previously stored readings (starting with
reading number 1) are overwritten.
Recalling Stored Readings
1. Momentarily press the CAL/RECALL key and then within 4 seconds
momentarily press the MODE/HOLD key. The last stored data point
location will be displayed (1 to 25). Each time the MODE/HOLD button
is momentarily pressed the next most recently stored data key will be
displayed.
2. After the last data point is displayed, pressing the MODE/HOLDkey again
returns the display to the beginning of the list.
3. Pressing the CAL/RECALL key at anytime stops the data retrieval process
and returns the meter to the normal measurement mode.
