3. Moduses and Functions
Standard Deviation
Instead of the min./max. value, the standard deviation is displayed
here, i.e. the mean quadratical error of the block temperature across
the last n measured values. After pressing ENTER, n = 0 is set and
the standard deviation will be recalculated.
Switch Test
Test menu for temperature switches, refer to
section 3.1.2 Measuring Instrument Setup Menu.
TC-Probe Menu
Calibration menu for thermocouples, refer to
section 3.1.2 Measuring Instrument Setup Menu.
Pt-Probe Menu
Calibration menu for resistance thermometers, refer to
section 3.1.2 Measuring Instrument Setup Menu.
mA-Probe Menu
Calibration menu for thermometers with temperature transducers,
refer to section 3.1.2 Measuring Instrument Setup Menu.
Display Averaging
The actual value of the block temperature displayed by the device
can correspond to the current temperature or be an average across
2 to 99 measured values. The average is continuously calculated
from the last n measured values according to the FIFO method. A
measuring rate of approx. 4 values/s, the following settings result
for the number of average values:
40, averaging for 10 s
99, averaging for 25 s
To ensure a steady display, we recommend averaging across 50
measured values, which corresponds to an integration time of 13 s.
