8.5
Calibration of the Grid Current Meter (IG)
Perform SETUP 3 (Fig.5).
1)
Switch the IG-IA switch to the IG position (4 Fig.1).
2)
The unit should be switched off.
3)
Adjust the output voltage of the external power supply to 0V.
4)
Connect the external power supply to the 2.2 Ohm, 5W resistor R4 situated on the rear
of the meter (current).
The polarity should be such as to produce a clockwise deflection.
5)
Increase the power supply voltage and check for a proportional increase in the grid
current (as measured by the VJ1000HP meter) and in the current supplied by the power
supply.
6)
Adjust trimmer R2 for a correct reading.
8.6
Calibration of Anode Measurement (IA)
Perform SETUP 3 (Fig.5).
Perform the procedure detailed for the calibration of the grid current measurement, but
instead connect the power supply to the R3 0.22 Ohm resistor found on the same board. Use
R1 to calibrate the IA meter.
