Manual voltmeter
If the
Keithley 2000 or Agilent 34401A multimeter
feature is
not
selected the program will ask you to put in a few
values from your voltmeter manually. These are used to calibrate the first sensing line of the PTC-04. This sensing line
will be used as reference meter for the calibration check.
Note:
the accuracy of the calibration depends on the precision of the voltmeter and the number of digits you enter.

Press
OK
to continue.
For the calibration of the internal reference meter, two series of 32 values are required. Once the internal reference
meter is calibrated the software will continue with the calibration check.
Note:
the decimal separator of the software is “.” not “,”. If one uses a “,” as decimal separator, the calculated
parameters will be incorrect.
