SAFETY INFORMATION
Warnings and Cautions
Toavoid electric shock, injury, or damage to this instrument andensure
that you use the meter safely,follow the safety guidelines listed below:
Read this operationmanual completelybefore using this device and follow
all safetyinstructions.
This device is for indoor use,altitude up to 2,000m.
Avoid working alone.
Use the device onlyas specified in this manual; otherwise, the protection
provided bythe metermaybe impaired.
Never measure Voltage with this meter.
Do not use this device ifitlooks damaged.
Inspectthe leads for damaged insulation or exposed metal.Replace
damaged leads.
Disconnect the power and discharge all high-voltage capacitors before
testing.
Be cautions when working above 70V DC or 33VRMS and 46.7V peak,

1. :Power ON or OFF
This button is used to toggle the power ON or OFF for the meter. Be
sure to press button completelyto be locked or released.
2. HOLD:Data Hold
Press the button to enable the data hold function. The function allows
operator to hold the displayed digital value.
Press this button momentarilyto trigger holding next reading.
Press this button for more than 1 second to exit the mode.
3. REC: Static Recording
Press "REC"button to enable the recording function.
Press "REC" button momentarily to cycle through maximum, minimum,
average and present readings. The MAX, MIN, AVG or MAX AVG MIN
indicator turns on respectively to indicate which value is being
displayed.
Press "REC"button for more than 1 second to exit the recording mode.
The beeper sounds a tone when a new MAX or MIN value has been
recorded.
The static recording capturesstable values and updates the memory; it
will notrecord the values are “OL” (overload) or below 10 count value.
4. REL: Relative function
The function shows the difference between the measured value and
the offset reference value.The displaymay show a non-zero value due
to the presence of test leads. You can use the relative function to nullify
the residual.
Press “REL” button to enable the relative function, and the "REL" sign
will be displayed. Press “REL” button again to renew relative value
again.
Press “REL” button for more than 1 second to exit the mode.
The relative function can operate in both auto and manual ranging
mode but the function cannotbe setwhen an overload value exists.
5. RANGE: Auto/ Manual Range
Press this button to select manual range and turn off the "AUTO"
indicator.Press this button momentarilyto step up a range ata time.
In auto-range, the "AUTO" indicator is lit and the meter will select an
appropriate range for resolution if a reading is greater than maximum
available range, "OL" (overload) will be displayed on the display. The
meter will select a lower range when reading is less than about 9 of
full scale.
Press this button for more than 1 second to select auto-range.

6. TOL: Tolerancemode
With capacitor into the terminals, press the "TOL" button to enable the
tolerance mode and set the display value to be a standard reference.
The “TOL” indicator will be indicated, and tolerance will be indicated on
the secondarydisplay. The meter range is locked also.
Press the “TOL” button momentarily again to cycle through 1%, 5%,
10% and 20% tolerance as desire. The alerting sign of “ ” will be
indicated accompanying. The beeper sounds a tone while the test
value is within the selected tolerance. If the test value is out of the
selected tolerance,the beeper will sound three tones.
This mode can not be enabled under following condition:
a. After setting the recording mode.
b. After setting the Comparemode.
c. The displayshows either OL or below 10 counts.
Press and hold this button for more than 1 second to exit tolerance
mode.
7. :Compare Mode
Press this button to enable the compare mode. The measuring range is
locked in this mode. The “ “ indicator will be shown, 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 “# #” is from 01 to 25. The primary display shows the present
measurement.In this state, it is readyfor testing. If the reading is out of
the high limit (Sign “ “ lit) and the low limit (Sign” “ lit), three
tones will be sounded, also the secondary display indicates “nGo”. If
the reading is within the high and the low limits, the beeper sounds a
tone, and the secondary display indicates “Go”. After 3 seconds or the
reading lower than 10 counts, the meter will return to readystate.
Press this button momentarily to select different settings for compare.
The secondary display will indicate “C01” to ”C25” according to which
comparison record has been selected. You can press and hold SAVE
button for more than one second to save comparisonsetfor next entry.
Press this button for more than 1 second to exit the mode.
8. HI/LO:High/Low limits
Press this button momentarily to see the High/Low limit value to be
used as compare mode. Press this button to cycle through High limit,
Low limitand present values on primarydisplay. The secondarydisplay
showed as “H # #”, “L # #” and “C # #” respectively. After 3 seconds
without pressing this button again, it will return present value display.
In the High/ Low limit setting mode, press this button momentarily to
toggle HI and LO limits for adjustment.

9. SET: sethigh/low limits for compare mode
Press the SET button for more than 1 second to enter the HI/LO limit
setting mode. The secondary display will flash “H01” and the primary
display will indicate the value of High limit. Following buttons will be
used for this setting mode:
a. (LEFT) or (RIGHT):select which digit will be adjusted.
b. (UP)or (DOWN): to Increase or decrease the current digit
value.
c. HI/LO: Select High or Low limit to be set.
d. SAVE:Press this button for more than 1 second to store the
setting value into the memory. The beeper will sound two tones
means theselected value has been stored. Ifthe current setting
can’t meetthe rule that the high limit mustequal or greater than
the low limit, the beeper sounds three tones (“BE-BE-BE”).
e. SET: Select next comparesetting. Press this button momentarily
to cycle through L01 (or H01) to L25 (or H25) then come back to
L01 (H01) setting.
Press the SET button again for more than 1 second to exit the HI/LO
limit setting mode.
10. Back-Lit
Press this button for more than 1 second to toggle backlit ON/ OFF.
Backlit turns off automaticallyafter setting period bysetup mode.
