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.
