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.

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.

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)

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.

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.
