Situation:
U1282A within the serial number range may not meet the specification for capacitance
measurement in 100nF range and below. This is due to improper open adjustment performed at
factory which the cable has been used to perform the open adjustment, has caused a negative
offset stored in the multimeter’s memory.
Solution/Action:
To verify whether the multimeter is impacted with capacitance measurement in 100nF range and
below:
1. Turn the knob to the Capacitance measurement position.
2. Manual set the range to 10 nF range.
3. Plug in one end of the Pomono 2BC-36 cable assembly across the capacitance measurement
terminal, leave the other end of the cable assembly open.
4. The U1282A should read between 0.8nF to 1.1nF, otherwise the “Open” calibration adjustment
was performed incorrectly.
To correct the multimeter capacitance measurement in 100nF range and below:
5. Unplug any cable from the multimeter’s terminal.
6. By referring to the service guide procedure
(http://literature.cdn.keysight.com/litweb/pdf/U1281-90002.pdf ), unsecure the meter to
enter into the calibration adjustment mode.
7. Turn the knob to the Capacitance measurement position.
8. Perform ONLY the “Open” adjustment in Capacitance measurement without any cable
connected to the multimeter.
9. Exit calibration adjustment mode after the “Open” adjustment is done.
10. Verify the “Open” adjustment has been performed correctly by repeating step 1 to step 4.
