carefully to avoid
electric shock hazard and serious damage to the instrument.
Do not twist clamp head while measurement. Measurement
should be incorrect if any pressure is applied to the clamp
head.
Do not touch any part of power line or the circuit to be
measured.

FUNCTION
Switch to " or ".
NOTE :
Do not touch trigger nor open clamp head until
POWER-ON INITIALIZE is completed and LCD
indicates 0
±
1 digit.
Supporting Functions :
Zero-Adjustment, Difference Measurement, Display Hold (Refer
to 4-5 and 4-6).
When taking measurement in 4000mA range, to reduce
geomagnetic effect to the measurement, zero
adjustment by POWER-ON INITIALIZE must be taken
just in front of a conductor to be clamped, fixing the
clamp head angle on measuring position.
NOTE :
LCD indication may not return to 0mA by
geomagnetic effect if changing clamp head angle after
measurement taking clamp head away from a
measured conductor.
When measuring low current at 1000mA or lower, take
zero adjustment by POWER-ON INITIALIZE for every
measurement.
LCD indication may not return to "0" by magnetic effect,
if high current is instantaneously applied during high
current measurement at 100A or higher, or regular
measurement in each range.
Under 4000mA range measurement,
±
15mA current
fluctuation from measuring value is not displayed on
LCD by internal control.
Zero-point
fluctuation
occurs
depending
on
temperature alteration of measurement environment
that could cause LCD indication not to return to "0" or
large measurement deviation.
NOTES : Following instructions are important to take
an accurate measurement.
4000mA range needs a few seconds until LCD
indications become stable.
Open clamp head 15mm or wider and close it softly. Detach
fingers from trigger after clamping a conductor.
Read the measurement value on LCD.
NOTE :
After measurement, unclamp from the conductor and set

5-2. DC CURRENT MEASUREMENT ( mA / A)
Dark Current :
mA-level low current that is used after turning off the engine by such as
car security system or audio settings back-up. Too much dark current
causes battery runs out, but its measurement was difficult. SK-7830 solved
this problem and make it quick and easy.
Clamp-on a minus cable of car battery.
Read the measurement value on LCD.
NOTE :
The values should be minus (
−
) if the current flows
opposite direction of "
⇒
" mark on clamp head.
If measurement value is higher than the specified value, check if
any of car lamps remain lighting.
NOTE :
POWER-ON INITIALIZE
does not work properly.
The specified dark current value becomes different if the
optional electric components such as car navigation or
security equipments are attached. In that case, refer to
their user's manuals for details.
Measurement value should be
incorrect.
NOTE :
Especially for the cars that ECU
or other electric components
keep working for a certain
period of time after turning off
the engine, or have LCD fuel
meter.
Cannot measure dark current.
Turn the all lamps off.
Leave the car engine turned off for about 15 minutes after
setting battery cable into the measurable condition. All electric
components such as door lamp, room lamp, and headlight
must be turned off. Lock the all doors if measuring car has
remote-control door lock function.
NOTE :
Leaving time is different depending on the car
functions, especially for the cars that ECU or other electric
components keep working for a certain period of time after
turning off the engine, or have LCD fuel meter.
NOTE :
Cool down the engine before measurement, in case that
measuring cable is close to the engine.
Put the clamp head close to a battery cable to be measured. Set
