INITIAL PREPARATION
Each meter is supplied complete with batter-
ies.
Remove the back cover, unwrap the batteries
and install them while paying attention to the
polarity.
To prepare the instrument for use, connect a
PT-100 temperature probe to the connector
located on the top of the instrument.
To switch the HI 955201 and the HI 955202
on, press the ON/OFF key.
To switch the HI955301 and the HI 955302
on, press the TEMP key.
HI 955201 and HI 955301 have a single probe
connection.
HI955202 and HI955302 have two probe con-
nectors.
With the meter facing you, channel #1 is the
first connector on the top left hand side.

If the PT-100 temperature probe is not con-
nected to the instrument, the meter will dis-
play and print "----" to alert the user.
This also indicates the possibility of a broken
probe cable. The channel is displayed with
"CH" and the number of channel (dual chan-
nel versions only).
Note: To ensure accurate readings it is rec-
ommended that the temperature probes
be connected to consecutive channels
beginning with channel #1. If only one
probe is used, it must be connected to
channel #1.
To maximize battery life, the display is
automatically switched off after 5 minutes
of non-use. However, the meter will con-
tinue to monitor (if in the logging/recording
mode) temperature.
To revive the display, press the ON/OFF
key (HI 955201 and HI 955202 only) or the
TEMP key (HI 955301 and HI 955302 only).
