, k factor, quick final value extrapolation
This function can only be used to the full when used with
testo Comsoft software. It is particularly suited to slow temperture
probes with a large thermal mass.
Measuring: During a test measurement, a jump in temperature is
recorded with an EEPROM probe.
The time constant of probe under given conditions for quick final value
extrapolation is determined and stored in the instrument via the
automatic learning function available in the PC software.
You can set and change this value in the instrument (in main menu
under PROBE - T
95
- fast). With the help of the k factor a small
change in temperature in the starting phase of a temperature jump is
amplified and extrapolated to the expected final value.
k= 0: Function without effect.
k=50.00 Maximum amplification possible
Depending on the probe, the optimum k value is between 0 and 50. If
the set k value is too small for the probe, the display reacts too slowly
to a temperature jump. If the k value is too big the displayed value
overshoots.
(Please refer to the Comfort software instruction manual for more
detailed information).
For quick measurements on location, assign one of the function
buttons with t-
95
and set the location required. Activate the function
by pressing the function button (the measurement on location must
correspond physically to the previous practice measurement). The
function is deactivated by pressing the function button again.
