If the temperature probe or a calibration test
plugs is not connected to the channel input,
the meter will display 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 (four chan-
nels versions only).
Note: To ensure accurate readings it is rec-
ommended that the temperature probes
be connected to consecutive channels
beginning with channel #1. For ex-
ample, if only one probe is to be used,
it must be connected to channel #1. If
2, 3 or 4 probes are to be used, they
must be connected to channels 1, 2,
3, and 4 in ascending order.
To maximize battery life, the display is auto-
matically switched off after 5 minutes of non-
use. However, the meter will continue to monitor
temperature (if in the logging mode) .
