This instrument was designed in compliance with IEC1010-1& IEC1010-2-032
safety guideline relative to electronic equipment.
For your own safety and to avoid damaging the instrument you are
recommended to follow the procedures described in this manual and read
carefully all instructions preceded by this symbol
Before and during measurements keep to the following instructions:
●Do not take current measurements in wet places
●Do not take the measurements in the presence of explosive gas and
combustibles or in dusty places

manufactured for measuring AC/DC current below 600V line Measure, it
adopt the latest CT technology and digital integrated technology. No exposed
metal conductor in the Clamp and no-contact measure model mean current
measure operation more safer and quicker. Super large Caliber is
particularly suitable for thick wire current measure. This meter is widely used
in electric power, communication, meteorology, railway, oil field, architecture,
measuring, teaching research unit, industrial mining enterprises, etc.
The instrument with current peak value holding, data holding, data storage
and other function. Equipped
With USB interface, communication line and supervision software, this meter
could achieve current online monitoring, show the real time current condition
via computer, with consult historical data, saving, print and other functions.

VIII. Method of Operation
1. Switch On/Off
Press POWER key to switch on, LCD display, in test mode, press
POWER key to switch off. The meter LCD will twinkling 30 seconds after
booting 5 minutes later,then automatically power off. While the LCD is
Twinkling, Press POWER ,HOLD or READ ,the meter will keep working
for 5 minutes. If LCD display is darker, maybe the battery voltage is too low,
please replace batteries.
2. Current Measure
High voltage, very dangerous！Only qualified personnel
after training could conduct operation on it. The operator
should obey safety regulations; Otherwise there will be the
danger of electric shock resulting in personal injury or
casualty.
Dangerous! Can not be used to test voltage higher than
600V. Otherwise there will be the danger of electric shock
resulting in personal injury or casualty.
(1).Power
(2). Press / key to choose the kind of measurement. Adjust zero
before DC measure, the DC positive direction should toward the meter
front cover.
(3).In Current measure procedure, Measured wire should at
approximately the geometric center of the
clamp(location:”A”)(Attention:Measured wire in Location”B”will make
error increasing +2%, and in location”C”would make error increasing
-2%)
(4).Read the LCD display data, In case ”OL A”symbol was displayed, it
means that current of measured line is beyond the maximum limit of this
Meter; with this case, please choose Meter with much higher range limit.

3. Peak Value Holding
Under the normal testing mode,press PEAK button(last more
than 3 seconds), display”PEHd”, That means the meter will
display and automatically keep the maximum value in the test.
Release the PEAK to exit from PEAK testing mode,
returning to normal testing mode.

4. Data Hold/Cancel/Storage/Consult/Delete
(1).Pressing HOLD key for a short time in the course of measurement (less
than 3 seconds), HOLD symbol will display, the meter will hold current
measuring data and automatically stored in the memory with a code; press
HOLD key again to release the hold state, and the meter continues its
measuring; in case stored data reached to 99 groups, press HOLD key again,
the “FULL” symbol will display, which means storage memory is full; press
HOLD key to cancel “FULL” flickering and return to measuring mode.
(2).Press READ keys to enter into data access mode and display Unit 1
storage data automatically; and then press HOLD key again to turn the page
of stored data; NULL will display when there is no data in stored in the
memory, press READ key to exit data access mode.
(3).After entering into data access mode, press HOLD key for more than 3
seconds will clean up all stored data; when the leaker displaying “dEL”
symbol, it means that it has finished cleanup process, and then return to
measuring state automatically.
5. Data Upload
Make good connection of company with RS232 communication wire of the
Tester, switch on the Tester and run monitoring software, and if the software
displays that interface is open and the connection is successful, then it can
read the stored historical data, upload to company and preserve.
Monitoring software has the function of online real-time monitoring and
historical inquiry, dynamic display, with the maximum, minimum, and
average value indication, with alarm value settings and alarm indicator, and
the function of historical data access, reading, preserve, print and other
functions.

VII. Battery Replacement
Warning! Make sure the battery cover is well closed
before measurement, otherwise there will be danger.
Take note of the battery polarity, otherwise it may
cause damage to the instrument.
If the battery power is not enough, please change in
time.
Take out the batteries if you expect not to use the
meter for a long time.
1．“ ”is displayed when the power voltage is lower than 5.2V, indicating
that the battery should be replaced.
2. Press POWER key, make sure the meter is power off. Open the battery
cover, replace new batteries and close the battery cover.
