While the switch is pressed on the Head Recognition Adapter the ON/OFF
output should stay at + 15V. When releasing the switch, the level should be
approx. + 5V.
ANALOG INPUT (8152A IN)
20. In MEASure mode select Autoranging OFF and Display in W.
21. Connect the Test Cable (P/N 15414--61603) from the P.CTRL receptacle to the
BNC connector marked with 8152A IN on the Test/Cal Box and ZERO the
HP8153A.
22. Connect the Test Cable to the ON/OFF receptacle and select the -20dBm
range using the Up Down keys.
23. Check that the HP8163A display shows approx. 12.500.
P.CTRL
24. Change the input sensivity of the oscilloscope to 0.05V/DiV and
25. Watch the DC level displayed on the oscilloscope and connect instead of the
Head Recognition Adapter the HP81520A or HP81521B Optical Head. 0
26. After a few seconds, the P.CTRL voltage should change from approx. 150
mV to approx. 40 mV (HP81521B) or from approx. 130 mV to approx. 30
mV (HP81520A).
IB. Function Test using a HP 81530/31/32 or HP
81536A
Sensor Modu le. The Function Test given in this section is using the HP 81530A,
HP 8153IA, HP 81532A, or HP 81536A Sensor Module to check the HP8153A
Multimeter Mainframe.
Note If you have an HP 81533A and a Test/Cal Box, it is preferable to
perform the function test with these. Go to “lA. Function Ibst
