INSTRUMENT OPERATION - Connect probes

via the socket(s) located at the top of the instrument.

(The Therma Differential uses a miniature type K

thermocouple connector and the AquaTemp uses

a 6 pin Lumberg screw locking type connector).

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.

HOLD - Press the HOLD button to stop

measurements, press again to continue measuring.

AUTO-OFF - The unit will switch off automatically

after 10 minutes. To disable auto-off press the

HOLD button while switching on the instrument

(this is reset when the instrument is switched off).

OPEN CIRCUIT/FAULTY PROBE - If the

probe has developed an 'Open Circuit' fault the

instrument will display 'Err'.

SENSORS - The Therma Differential should only be

used with type K (Nickel Chromium/Nickel

Aluminium)

thermocouple plugs (to BS EN

50212).

The AquaTemp can be used with either an

interchangeable thermistor probe or a type T

thermocouple probe fitted with 6 pin Lumberg

screw locking connectors. This instrument is

designed to be compatible with ThermoWorks’

probes.

BATTERY REPLACEMENT - The instrument

will display a low battery symbol 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 three AAA batteries located

under the rear case half that is held in place by

six screws. Check the seal for damage and

carefully replace the rear case half and tighten

the screws.
