Troubleshooting

Do one of the following:
•
With a full set of thermocouples attached to the logger, and the logger
connected to a PC running Insight, open the Logger Reset dialog (p. 41)
or the Diagnostic section of the Communications Setup dialog (p. 40); this
shows current probe temperatures –
or
...
•
Set up the system as if to monitor a profile run using hardwired telemetry
(see p. 55 for details), and note the temperatures registered by the
thermocouples as they are displayed in Insight –
or
...
•
To test the thermocouples alone, use a digital thermometer (of a type to
match the thermocouple type) and attach it to each thermocouple in turn.
Proceed as follows.
1. Note readings first at ambient temperature: thermocouples registering no
data in Insight, or an open circuit with a digital thermometer (*OC* in the
Communications Setup dialog), may be broken. Inconsistent readings may
indicate an intermittent short circuit.
2. If a satisfactory ambient reading is recorded, apply heat to the
thermocouple-tip via fingers or other heat source. An increased
temperature should register.
○
If the reading does not change, the thermocouple is short circuit or has
other damage and must be replaced.
○
If the temperature shows a decrease, the thermocouple connections are
reversed.
3. Confirm correct operation at 100°C/212°F by placing the thermocouple-tip
in freshly-boiled water.
4. Replace any damaged thermocouples and test again.
