Each meter is supplied complete with batteries. Remove the back
cover, unwrap the batteries and install them while paying attention
to the polarity.
Alternatively, connect the a 12 Vdc voltage adapter to the power
adapter plug.
To prepare the instrument for use, choose the most appropriate
temperature probe(s) for your application (see "Accessories") and
connect it (them) to the the instrument.
All the probes have been precalibrated at the factory and no
calibration is needed.
With the meter facing you, channel #1 is the first connector on the

The batteries charge status or "LINE" message
(if external power adapter is connected) will be

The meter is now ready to operate.
To maximize battery life, the meter is automatically switched off after a
user selectable period of non-use (this feature is enabled and set to 5
minutes by default; it can be disabled or changed through setup
code #40).
If in logging mode, after the period of non-use, the meter will
continue to monitor the temperature periodically at the end of every
logging interval. Only the "LOG" indication will be visible on LCD.
While storing data in memory, during the sleep mode, the reading
will appear briefly on the LCD.
To reactivate the display press the ON/OFF key.
Note: When the use of an alternate function (FNC, CFM and LOT
INFO) is requested, press and hold the ALT key first and then
the second key.
