INITIAL PREPARATION
Each meter is supplied complete with batter-
ies. Remove the back cover, unwrap the bat-
teries and install them while paying attention
to the correct polarity (see "Battery Replace-
ment" section).
To prepare the thermometer for use, connect
a Pt100 temperature probe to the connector
on the top of the instrument.
To switch the HI 955201
and HI 955202 on, press the
ON/OFF key.
To switch the HI 955301 and
HI 955302 on, press the
TEMP key.
HI 955201 and HI 955301 are provided with a
single probe connection, while HI 955202 and
HI 955302 feature two probe connectors.
Looking at the display side, channel #1 is the
first connector on the top left hand side.
If no temperature probe is
connected to the thermom-
eter, it will display and print
"----" to alert the user.
This can also indicate a broken probe cable.
The channel # is displayed together with the
"CH" indication (dual channel models only).
Note: With dual channel models, if only one
probe is used, it must be connected to
channel #1.
