1. Points to be observed during operation
a.) Make sure to apply correct operating voltage as low or damaged battery will lead to measuring inaccuracies. If
„BAT“
is shown in the display or are the measurements obviously wrong the battery has been used up and needs to be
replaced.
Please note:
If the battery voltage falls even lower the voltage may not be sufficient for
„BAT“
to be displayed so that there will
be no
„BAT“
indication although the battery has been used up. We recommend to make it a rule to always check
the battery if the values indicated seem to be completely out of range.
b.) Make sure to maintain device properly and to operate it in accordance with the specification listed (do not throw,
knock etc.).
c.) Make sure that sensor and device are always subjected to the same temperature, i.e. try to avoid holding sensor
plug in your hand for a longer periode of time as well as subjecting device to an additional heat source as this may
result in measuring inaccuracies.
d.) Mains operation: When using a power supply unit please note that operating voltage has to be 10 to 12 V DC. Do
not apply overvoltage!! Cheap 12V-power supply units often have excessive no-load voltage. We, therefore,
recommend using regulated voltage power supply units. Trouble-free operation is guaranteed by our power supply
GNG10/3000.
Prior to connecting the plug power supply unit with the mains supply make sure that the operating voltage stated at
the power supply unit is identical to the mains voltage.
e.) The battery has to be taken out, when storing device above 50°C. It is recommended to take the battery out, when
storing device for a longer period of time
f.) The length of the measuring sensor (GTF300) can be reduced as desired so that it will be fully operational again
after sensor has been broken. To do so, please strip both wire ends for approx. 10mm and twist well. Measurements
are not possible as long as wire ends are exposed.
