I) INTRODUCTION
High Accuracy leakage clampmeter, model KM 2008, is
specially designed for measurement of AC leakage
current; It is a product with relatively small size, high
accuracy and perfect function compared with similar
instrument in the world. The meter could be widely used
in different fields such as electricity, communications,
meteorology, railroad, oilfield, construction, measurement,
scientific & research teaching institutes, industrial and
mining establishments.
Clamp core of this High Accuracy Leakage Clampmeter
adopts special alloy; in addition, with utilization of
magnetic shielding technology, it is almost free from
influences of external magnetic field so as to ensure high
precision, high stability and high reliability of perennial
continuous measurement.
This High Accuracy Leakage Clampmeter has RS232
interface. With the help of the software that we provide,
many function are available. For example, on-line
monitoring, historical data inquiry, active curve drawing,
indication of max, min and average value, alarm setting
and indication. There are also functions like saving to
documents and printing when connected to PC.
This High Accuracy Leakage Clampmeter could be
used for AC line current measurement and on-line current
measurement with voltage lower than AC600V; it also
have those functions as peaking holding, data holding
and data storage; with convenient use, it is an essential
tool for electrician safety testing.

VI) OPERATING PROCEDURE
1. Start-up, Shutdown
Press POWER key to start up, LCD will begin to display;
Press the POWER key again, the meter will shut down.
After starting up for 5 minutes, LCD will flick notes that
the meter will shut down automatically; After flickering
for 30s, it will shut down formally to reduce battery
consumption. In case you have pressed POWER key
when LCD was flickering, the leaker will continue to
work for 5 minutes. If LCD is very dark after starting
up, it might be caused by low-voltage battery, in this
case, please change battery immediately.
2. Leaker Measurement
Dangerous! Please don't use it to measure current
higher than 300A; otherwise there would be risk of
electric shock to cause personal injuries or equipment
damages
!
High voltage, extremely dangerous! Operators shall
strictly keep to safety rules; otherwise there would be
risk of electric shock to cause personal injuries or
casualties.
1) Power on.
2) Press down trigger to open clamp head and clamp
to-be-measured conductors. (clamp heads must be
totally closed)
!
Clamp live wire and null line together to measure
leakage current of electrical equipment. (Note: 2 lines)
Clamp earth wire is to measure grounding line leakage
current of electrical equipment. (Note: Single line)
Clamp main line is to measure total current of that main
line. (Note: Single line)

Attention! For your safety, when measuring heavy current,
after confirmed the completion of correct operating test,
please move the meter away from measured conductor,
In locations with difficulty to read out data, please use the
data holding function. If [DH] symbol displayed, please
exit data holding state first, and then do the test.

3) Read LCD display data. In case "OL mA"symbol
was displayed, it means that current of measured
line is beyond the maximum limit of this meater
3. Peak Hold
Pressing HOLD key continually in the course of
measurement (More than 3 seconds), the leaker will
capture current peak values of lines. 3 five times;
release the key, it then will return to measuring state.
4. Hold, Storage and Access Reading
1) Pressing HOLD key for a short time in the course of
measurement (less than 3 seconds), DH symbol will
display, the meter will hold current measuring data
and automatically stored in the memory with a unit
ID; press HOLD key again to release the hold state,
and the meter continues its measuring; in case stored
data reached to 60 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 HOLD + POWER keys to enter into data access
mode and display shows 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 POWER 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.

IX How to Change Battery
!
Warning! It is dangerous to carry out test when the
battery cover plate is not on its position
Please pay attention to the polarity of battery to avoid
damaging the meter.
Change the low battery in time
If you expect not to use the meter for a long time,
please remove the battery for storage.
-+
1) " " symbol means the battery is undercharge and
need to be replaced.
2) Press POWER key to shut down the meter; before
opening the battery cover, please confirm the meter
is in off position, and then replace with qualified new
battery; special attention shall be paid to the polarity
