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 (see also page 34).
To switch
HI 9171, HI 9174, HI 9181
and
HI 9184
on, press TEMP.
To switch
HI 9271
and
HI 9274

If the meter does not switch on check the batteries.
PROBE CONNECTION
Choose the most appropriate temperature probe(s) for your applica-
tion (see page 36) and connect it (them) to the probe connector(s)
located on the top of the instrument. All the probes have been
precalibrated at the factory and no calibration is needed.
HI 9171, HI 9181
and
HI 9271
take a single probe while
HI 9174,
HI 9184
and
HI 9274
can take up to four probes.
With the meter facing you, channel #1 is the first connector on the
top left corner.
If neither a temperature probe nor a calibration test plug is connected
to the instrument, the meter will display "°C ----" to alert the user.
This could also indicate that probe cable is damaged. "CH" and the
channel number are displayed together (HI 9174, HI 9184, HI 9274
only).
