INITIAL PREPARATION

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 a 12 Vdc voltage adapter to the power adapter
plug on the top of the instrument.
To prepare the instrument for use, choose the most appropriate
temperature probe(s) for your application (see "Accessories" section for
a complete list) and connect it (them) to the connector(s) on the top
of the instrument.
With the meter facing you, channel #1 is the first connector on the
top left hand side.
To switch the meter on, press the ON/OFF key.
The batteries charge status or "LINE" message
(if external power adapter is connected) will be
displayed on the LCD for a few seconds.
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 displayed.
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.
