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:

 1, averaging disabled

 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.
