4.1.2.1 Selecting the thermometer input channel and differential mode (A/B key)
The channel Select key ( A/B ) is used to change between channels and also to select the differential
operational mode, ( A – B ). The channel selection order is –
Channel A Î Channel B Î Channel (A – B) Î Channel A
A missing (or faulty) probe will be indicated on the display by a series of dashed lines.
In differential mode (when both channel A and channel B have probes connected), the screen will look
similar to the following example. The asterisk next to the ChA and ChB legends will alternate as
readings are updated.
The probe conversion indicator (bottom-left) displays the conversion method for the current reading
(and so will alternate if the two channels have different conversion methods).
4.1.2.2 Selecting relative temperature measurement (0 key)
The instrument displays a reading value relative to a fixed offset in Zero (or relative) mode. Press the
Zero ( 0 ) key to select this mode.
