Operating Instructions
for
Therma Plus 2 & 5
INSTRUMENT OPERATION
The instrument is switched on by using the "On/Off" button located on the front of the instrument. Apply the tip of
the probe, to the substance, medium or surface to be measured. The instrument reading may take seconds to
stabilise, depending on the nature of the measurement and the sensitivity of the probe.
BUTTON FUNCTIONS
To ensure the waterproof integrity of this unit, do not press buttons with sharp or pointed objects or pierce the front
label. On/Off - Switches the instrument On or Off. Hold - Allows the display to be "frozen" for ease of reading.
OPEN CIRCUIT/FAULTY PROBE
If the probe has developed an "Open Circuit" fault the instrument will display "-1".
BATTERY REPLACEMENT
Replace the battery immediately the "Lo Bat" illuminates, using a PP3, MN1604 or a direct 9 volt equivalent. The
battery is located under the cover at the rear of the instrument. Care should be taken when replacing the battery,
to ensure the rubber seal is not damaged and the seal is in good condition before replacing the battery cover. A
replacement sealing kit can be purchased - Order Code 830-630. Please note: these thermometers have an inbuilt auto-power off circuit to conserve battery life. The instrument will automatically turn off approximately two/
three minutes after the last button operation.
EMC/RFI
Readings may be affected if the unit is operated within a radio frequency electromagnetic field strength of approximately
3 volts per metre, but the performance of the instrument will not be permanently affected.
