4.1.4 Setting up Temperature measurement

To enable accurate resistance to temperature conversion to be carried out by the instrument, PRT or

characterisation data is required for both –

• temperature conversion algorithm, and

• temperature conversion algorithm coefficients

For Thermistors, characterisation data is only required for –

• temperature conversion algorithm coefficients

The data can be stored in either a Smart probe or the instr uments’ internal non-volatile memory

(Passive probe), each thermometer input channel stores one set of PRT/Thermistor characterisation

data. See the relevant section above for details on entering the data.

4.1.4.1 Temperature measurement with Smart probe (s)

If a Sm art probe is detected on a s elected input channel, the PRT calibration data is loaded directly

from the Smart pr obe. Smart probe data always takes precedence over the internal F100 coefficient

data (but does not overwrite the instrument data)

4.1.4.2 Instrument calibration

This is not usually a c ustomer option; refer to separate documentation.

4.1.4.3 Firmware Version

The firmware version is shown on the LCD when the instrum ent is first powered.

4.1.5 Smart Probe review

The Smart probe data can be viewed, but not changed on the F100. The Smart probe data contains

the following information.

0 = Smart probe data locked can not be changed from the instrument

1 = Smart probe data unlocked can be changed from the instrument

Any calibration data entered is retained for future use a Passive probe.
