General Safety Information
WARNING
CAUTION
The following general safety precautions must be observed during all phases of
operation, service and repair of this instrument. Failure to comply with these
precautions or with specific warnings elsewhere in this manual violates safety
standards of design, manufacture and intended use of the instrument. Keysight
Technologies assumes no liability for the customer’s failure to comply with these
requirements.
– Read this operation manual completely before using this device and
follow all safety instructions.
– This device is for indoor use at an altitude of up to 2000 m.
– Avoid working alone.
– Use the device only as specified in this manual; otherwise, the protection
provided by the meter may be impaired.
– Never measure voltage with this meter.
– Do not use this device if it looks damaged.
– Inspect the leads for damaged insulation or exposed metal. Replace
damaged leads.
– Disconnect the power and discharge all high-voltage capacitors before
testing.
– Be cautious when working with voltages above 60 V

2 Features and Functions
Static Recording
The static recording mode can record the maximum capacitance and minimum
capacitance you measured. Furthermore it is able to perform averaging on the
measurement result. Static recording captures only stable values and updates the
memory; the meter will not record values that are OL (overload) or below 10
counts.
The operational procedures are described below:
1 Press REC key momentarily to enter the static recording. The present value is
stored to memories of maximum, minimum and average. The MAX, AVG, MIN
annunicator will be lit.
2 Press this key momentarily to cycle through maximum, minimum, average and
present readings. The MAX, MIN, AVG or MAX AVG MIN annunciator turns on
respectively to indicate which value is being displayed (see Figure 2-1).
3 The beeper will beep once when a new MAX or MIN value has been recorded.
4 Selecting static recording mode as auto range, it will record the value of MAX,
MIN or AVG for different ranges.
5 Press REC key for more than 1 s to exit recording mode.
6 The auto power-off feature will be disabled and the will be turned off
as recording mode.

The data hold function allows the users to hold the displayed digital value. Refer
to the following procedures to enable data hold:
1 Press HOLD key to freeze the displayed value and enter manual trigger mode,
and the sign of DH will be displayed.
2 Press HOLD key again to trigger another new measuring value updated to
display. The sign of DH will be flashed before the new updates.

Tolerance Mode
The tolerance mode has 1%, 5%, 10%, and 20% tolerance ranges. To enter the
tolerance mode, insert a standard value into the socket. Press the TOL key to set
the display value as the standard reference. Similarly, the DH value which appears
on the primary display can be used as a standard value to sort the components.
Press TOL key again to cycle through 1%, 5%, 10% and 20% tolerance and select
the desired tolerance. The meter range locks as tolerance mode.
This mode can not be set under following condition:
– After setting the recording mode.
– After setting HI/LO Audible Alert mode.
– The tested display is either OL or below 10 count.
This function is designed for sorting the values. The beeper will beep three times
when the reading is out of the selected tolerance. A single beep represents that
the reading is within the selected tolerance.
To exit tolerance mode, press and hold TOL key for more than 1 s

These initial sets can be modified, please refer to the Setting HI/LO limits for
detailed description. Besides that, the power-on option can be used to restore the
default factory settings.
The following procedures will guide you on how to set compare mode:
1 Press key momentarily to enter HI/LO Audible Alert mode. The
meter locks range in this mode. The annunciator will be indicated, and
the secondary display will indicate C01 to C25 or the previously saved set
during last operation. The first left digit means comparison mode. The last
two digits indicate current comparison set. The primary display will indicate
the present measurement. The meter is ready to test.
2 Press key momentarily to select different sets. The secondary
display will indicate C01 to C25 according to which comparison set has
been selected. Press and hold SAVE key for more than 1 s to save
comparison set for next entry.
3 Press HI/LO key to cycle through the HI/LO value used for comparison
and back to ready mode. The HI/LO limits will be briefly indicated on the
primary display, and then back to the ready mode.
4 If the reading is out of the HI/LO limits, the beeper will beep three times
and the secondary display will indicate nGo. If the reading is within the
HI/LO limits, the beeper will beep once and the secondary display will
indicate Go. After 3 s, the meter will return to ready state.
5 Press and hold the key for more than 1 s to exit audible alert
mode.

Setting HI/LO limits
To set the HIGH and LOW limits for compare mode, refer to the following
procedures:
1 Press and hold SET key for more than 1 s to enable the HI/LO limit setting
mode.
2 The secondary display will flash L01 and the primary display will indicate the
limit value. The following keys will be used for this setting mode:
a (Left) or (Right): select which digit to be adjusted.
b (Up) or (Down): to Increase or decrease the current digit value.
cHI/LO: Select High or Low limit to be set.
dSAVE: Press this key for more than 1 second to store the setting value into
the memory. The beeper will beep twice, meaning the selected value has
been stored. If the current setting does not meet the rule that the HI limit
must be equal or greater than the LO limit, the beeper will beep three
times.
3SET: Select next compare setting. Press this key momentarily to cycle through
#01 to #25 then return to #01 setting according to Hi/LO limit.
4 Press and hold the SET key for more than 1 second to exit the HI/LO limit

CAUTION
NOTE
Capacitance Measurement
To avoid possible damage to the meter or the equipment under test,
disconnect circuit power and discharge the capacitor before measuring
capacitance.
Capacitance is the ability of a component to store an electrical charge. The unit of
capacitance is the farad (F). Most capacitors are within the range for nanofarad
(nF) to microfarad (µF). The meter measures capacitance by charging the
capacitor with a known current, measuring the resulting time of charging period,
and then calculating the capacitance. The larger capacitors will take longer time
to charge. The sign of C flashing means that the meter is charging capacitor. To
improve the measurement accuracy of small value capacitance, press REL with
the alligator clip leads open to subtract the residual capacitance of the meter and
leads.
Measuring tip: For measuring capacitance >1000 µF, discharge capacitor first
and then select a suitable range to measure it. This will speed up the measuring
time to achive the correct value.
1 Power-on the meter.
2 To test for capacitance, keep an open circuit on the test leads and press REL
key to subtract the residual capacitance of the meter and leads.
3 Insert the legs of the capacitor into + and – input sockets respectively. Ensure
that the polarity of the capacitor’s leg are correct.
4 Remove your hands from capacitor to allows it to be tested.
5 Read the measurement on the display.

The meter is reserved with communication capability. The optional IR-USB
package comes with full optical isolated cable and software. This function enables
the user to record the data easily. Refer to the following procedures to set up the
communication between your meter and personal computer (PC).
1 Connect one side of the cable to the meter with the Keysight Logo facing up
and connect the USB connector to the PC.
2 Run the software to transfer the data to the PC for your applications.
3 To remove the cable, press and pull the snap ends on each side of the cable
that is connected to the meter.
