INSTRUMENT OPERATION
- Where applicable (Therma 20
and Therma 22) connect a probe via the socket located at the
top of the instrument, screw in the collar of the plug, finger
tight, to ensure a secure connection (do not over tighten).
Switch the instrument on and apply the tip of the probe to
the substance or medium to be measured. The instrument
reading may take a few seconds to stabilize, depending on
the nature of the measurement and sensitivity of the probe.
OPEN CIRCUIT/FAULTY PROBE
- If the probe has developed
an 'Open Circuit' fault the instrument will display 'Err'.
SENSORS
- The ThermaCheck incorporates a fixed thermistor
probe. The Therma 20 operates with an interchangeable
thermistor probe. The Therma 22 operates with either a
interchangeable thermistor or type T thermocouple probe.
These instruments are designed to be compatible with
ThermoWorks manufactured probes.
CHANGE FROM FAHRENHEIT TO CELSIUS
- Press and
hold the “ON/OFF” button for 5 seconds at start up and the
displayed temperature will change from °F and °C.
BATTERY REPLACEMENT
- The instrument will display 'LO
BAT' to warn that the batteries will need changing soon. The
instrument continues to measure accurately but after further
usage the instrument will display 'flat bat' and shutdown.
Replace the batteries with three AAA batteries located under
the rear cover that is held in place by a single screw.
