For a given measurement session, this meter can record the highest (MAX) and the lowest (MIN)
readings for later recall.
1.
Press the MAX-MIN key momentarily to access this mode of operation (REC icon appears)
2.
The meter is now recording the MAX and MIN readings.
3.
Press the MAX-MIN key again to view the current MAX reading (MAX icon appears). The
reading on the display is now the highest reading encountered since the REC icon was
switched on (when the MAX-MIN key was first pressed).
4.
Press the MAX-MIN key again to view the current MIN reading (MIN icon appears). The
reading on the display is now the lowest reading encountered since the REC icon was
switched on (when the MAX-MIN key was first pressed).
5.
To exit the MAX-MIN mode, press and hold the MAX-MIN key for at least 1.5 seconds. The
meter will beep, the REC-MAX-MIN icons will switch off, the memory will clear, and the meter
will return to the normal operating mode.
Display Backlight
To turn the display backlight ON or OFF, press and hold the backlight
key for at least 1.5
seconds. The meter will beep when switching the backlight ON or OFF unless the beeper is
disabled as described in the Setup Mode section of this user guide.
System Reset
If the meter’s keys become inoperable or if the display freezes, the Reset button can be used to
reset the instrument.
1.
Use a paper clip or similar item to momentarily press the reset button located on the lower right
side of the instrument under the snap-off compartment cover.
2.
After pressing the Reset button, switch the instrument ON by pressing and holding the
POWER key for at least 1.5 seconds. If using the power adaptor, unplug the adaptor and then
plug it back in again to power the meter.
AC Power Adaptor
This meter is normally powered by six (6) 1.5V ‘AA’ batteries. However, an optional AC 9V power
adaptor is available. To use the adaptor, insert the power adaptor plug into the jack on the bottom
right side of the meter (under the snap-off compartment cover); plug the other end of the adaptor
into an AC power source. The meter will now be permanently powered (as long as the adaptor is
used) and the power key will be disabled.
