Calibration Record for Agilent E3633A/E3634A
Step Calibration Description
Measurement 
Mode (DVM)
Supply Being 
Adjusted
1 Unsecure the power supply (see page 62).
2
Turn on ‘‘CAL MODE’’ (hold down ‘‘Calibrate’’ and ‘‘Power’’ keys as 
you turn on the power supply until you hear a long beeps).
3 Move down menu to ‘‘CAL SETUP 1’’ (press ‘‘Calibrate’’ key). Voltage Calibration
4
Calibrate DAC and select the low point for voltage calibration; ‘‘START 
BITCAL’’ appears for about 3 seconds and the display counts down 
numbers from 30 to 0. Then, ‘‘V LO 0.5000 V’’ appears on the display 
(press ‘‘Calibrate’’ key and wait about 30 seconds; then change the 
display to match the DVM reading).
V
DAC and low voltage 
point calibration
5
‘‘V MI  10.000 V’’* or ‘‘V MI 25.000 V’’** appears on the display (press 
‘‘Calibrate’’ key; then change the display to match the DVM reading).
V
Middle voltage point 
calibration
6
‘‘V HI 19.500 V’’* or ‘‘V HI 49.500 V’’** appears on the display (press 
‘‘Calibrate’’ key; then change the display to match the DVM reading).
V
High voltage point 
calibration
7 ‘‘CAL SETUP 2’’ now appears on the display (press ‘‘Calibrate’’ key). V OVP calibration
8
‘‘CAL SETUP 3’’ now appears on the display (press ‘‘Calibrate’’ key; 
then connect 0.01 
9 resistor across the output terminals).
Current calibration
9
‘‘I LO 0.500 A’’* or ‘‘I LO 0.200 A’’** appears on the display (press 
‘‘Calibrate’’ key; then change the display to match the computed current 
through the resistor).
A
Low current point 
calibration
10
‘‘I MI 10.00 A’’* or ‘‘I MI 3.500 A’’** appears on the display (press 
‘‘Calibrate’’ key; then change the display to match the computed current 
through the resistor).
A
Middle current point 
calibration
11
‘‘I HI 19.5000 A’’* or ‘‘I HI 6.900 A’’** appears on the display (press 
‘‘Calibrate’’ key; then change the display to match the computed current 
through the resistor).
A
High current point 
calibration
12 ‘‘CAL SETUP 4’’ now appears on the display (press ‘‘Calibrate’’ key). A OCP calibration
13 Press ‘‘Calibrate’’ key, then press ‘‘Power’’ switch. Exit CAL MODE
