Safety Notices
CAUTION
A CAUTION notice denotes a hazard. It calls attention to an
operating procedure, practice, or the like that, if not correctly
performed or adhered to, could result in damage to the prod-
uct or loss of important data. Do not proceed beyond a CAU-
TION notice until the indicated conditions are fully
understood and met.
WARNING
WARNING notice denotes a hazard. It calls attention to an
operating procedure, practice, or the like that, if not cor-
rectly performed or adhered to, could result in personal
injury or death. Do not proceed beyond a WARNING notice
until the indicated conditions are fully understood and met.

Quick Start
1Press to power- on the meter.
2To test for capacitance, keep an open circuit on the test leads and press to subtract the
residual capacitance of the meter and leads.
3Insert the capacitor legs into +and –input terminals respectively. Ensure that the polarity of
the capacitor’s leg are correct.
4Remove your hands from capacitor to allow it to be tested.
5Read the measurement on the display.
CAUTION
Measuring tip: For measuring capacitance of more than 1000 µF, first, discharge the
capacitor then select a suitable range to measure it. This will shorten the measuring
time to achieve an accurate value.
Degradation of some product specifications can occur in the presence of ambient
electromagnetic (EM) fields and noise that couples to the product’s powerline or I/O
cables. The product self-recovers and operates to all specifications when the source of
the ambient EM field and noise are removed or the product is protected from the
ambient EM field or the product cabling is shielded from the ambient EM noise.

To power ON or OFF Press
To enable data hold function Press
To trigger holding next reading Press momentarily
To exit data hold mode Press for more than 1 s
To enable recording function
•The beeper will beep when a new MAX or MIN value has
been recorded.
•The static recording captures stable values and updates
the memory. It will not record values that are overloaded,
OL or below 10 count value.
Press
To cycle through maximum, minimum, average, and present
readings
•MAX, MIN, AVG or MAX AVG MIN annunciator will be
turned on respectively to indicate which value is being
displayed
Press momentarily
To exit the recording mode Press for more than 1 s
To enable relative function
•Relative function shows the difference between the
measured value and the offset reference value. The
display may show a non-zero value due to the presence
of test leads. Use the relative function to nullify the
residual.
•Relative function can operate in both auto and manual
ranging mode but the function cannot be set when an
overload value exists.
•RELannuciator will be displayed.
Press
To renew the relative value Press again
To exit relative mode Press for more than 1 s

Actions Steps
To select auto-range
•In auto range mode, the AUTO annunciator is displayed
and the instrument will select an appropriate range for
resolution if the reading is greater than the maximum
available range. OL will be displayed.
•The instrument will select a lower range when the
reading is less than 9% of full scale.
Press for more than 1 s
To enable the tolerance mode and to set the display value
as a standard reference
•TOLannunciator will be displayed.
•The tolerance will be displayed on the secondary display.
•The instrument range will be locked.
Press
To cycle through 1%, 5%, 10% and 20% tolerance
•will be indicated.
•Beeper will beep once if the test value is within the
selected tolerance. If the test value is out of the
tolerance, the beeper will beep three times.
•This mode cannot be enabled under the following
conditions:
•After setting the recording mode
•After setting the compare mode
•Display showing either OL or below 10 counts
Press momentarily
To exit tolerance mode Press and hold for more than 1 s
To enable compare mode
•Measuring range will be locked
•will be displayed and the secondary display will
indicate C # #, meaning which set has been used for
compare mode. The two right digits indicate current
compare set. The ##range from 01 to 25.
•The primary display shows the present measurement. In
this state, it is ready for testing.
•If the reading is beyond the high limit, will be
indicated. will be indicated if the reading is out of the
low limit. The beeper will beep three times and the
secondary display will indicate nGo.
•If the reading is within the high and low limits, the beeper
will beep once, and the secondary display will indicate
Go. After three seconds or when the reading is lower
than 10 counts, the instrument will return to its ready
state.
•The secondary display will indicate C01 to C25 according
