M-142 Multifunction Calibrator
MEATEST, s.r.o.

User Manual v54
If frequency larger or smaller than the calibrator’s range is entered, the calibrator displays an error message:
„Value is too large (small)“.
Generation of calibrated voltage
The multifunction calibrator provides calibrated DC and AC voltage. Output terminals for voltage ranges are
labeled “ Hi “ and “ Lo “ at the front panel. Depending on the setting of the calibrator, voltage up to 1000 Vef
can be present at the terminals .
DC voltage range is 0 to 1000 V.
AC voltage range is 100
V to 1000 V.
Control in the voltage mode
•
Press “U” button on the calibrator and then select AC or DC mode by pressing “DC-AC” button. The
display shows the following data:
*
main data of set voltage
*
relative deviation
*
uncertainty of output voltage
*
frequency (when AC voltage is generated)
*
total value of output voltage when non-zero relative deviation is set
•
Set the desired value of voltage, including polarity when necessary, frequency and relative deviation. The
signal is yet not connected to the output terminals. The information section of the display shows the symbol
which informs about the disconnection of output terminals.
•
Press OUTPUT button.
•
Red LED is lit above the OUTPUT terminals to signal the connection of the signal to the output terminals;
the information section of the display shows the symbol
.
•
Calibrated voltage corresponding to set parameters is present at the output terminals.
