Probe Accuracy / Device Accuracyg 1700 / -20 / -30; Possible Errors; Configuration - GREISINGER G1700 Betriebsanleitung

H86.0.0X.6C-02
To receive high exchange accuracy without necessity of additional adjustment we
recommend the usage of temperature probes from the class "A" or "AA".
6.2 Probe accuracy/device accuracy G 1700 / -20 / -30
The display unit and the probe of instruments with fixed mounted probes have been
matched very accurate ex works, see chapter 13 Specification.

6.3 Possible errors

• Immersion depth
For measurements in liquids the probe should be immersed sufficiently deep
(depending on probe diameter, at least 20 mm with Ø 3 mm and 10 mm with Ø
1.5 mm) and subsequently stirred.
When measuring gases the probe should also emerge as deep as possible in
the gas to be measured (e.g. when measuring in channels/pipes) and the gas
should flow around the probe at sufficient flow.
• Surface effects and bad heat transfer
For surface temperature measurements special surface probes are necessary.
Surface quality, heat transfer and ambient temperature have an influence on
the measurement result.
• Cooling (evaporation)
For air temperature measurements, the probe should be dry, otherwise it can
be possible that a too low temperature could be measured.
• Response time
Before reading the measured value at the measuring process, it is necessary to
wait a sufficient time (see chapter 13 Specification – Response time
