5. MEASUREMENT PROCEDURES
5-1. PREPARATION FOR USE
1. INSTRUCTION MANUAL
Read INSTRUCTION MANUAL carefully to understand the specification and
functions correctly. 「3. SAFETY PRECAUTIONS」is higly important for safety
measurement.
2. BATTERY
Before using this instrument, install 2 of 1.5V (L)R03 (AAA) batteries refering to
「6-1.BATTERY REPLACEMENT」. Replace them in the same way when "BAT"
lights up on LCD.
3. OVERLOAD INDICATION
"OL" lights up on LCD if measurement value exceeds maximum indicatable value
of each measurement range (4050 digits).
4. AUTO POWER OFF
Power turns off automatically after approx. 15 minutes of last FUNCTION Switch
operation to conserve battery life. (Small current consumption remains. After
measurement, be sure to set FUNCTION Switch to "
".)
To cancel it : Hold down DH Key and turn the power on. ("APO" disappears)
5. SYMBOL MARK
The following symbol marks shown on the instrument and instrunction manual are
listed in IEC 61010-1 and ISO 3864.

6．MAINTENANCE
6-1. BATTERY REPLACEMENT
WARNING
To avoid electrical shock, detach instrument and test leads from circuit when
to replace battery. Set FUNCTION Switch to "OFF".
Replace the batteries when "BAT" lights up on LCD.
1.
Turn the power off and detach test leads from the circuit.
2.
Unscrew Baterry Cover and remove exhausted batteries.
3.
Insert 2 pcs of new 1.5V (L)R03 (AAA) batteries in correct polarity.
4.
Fix Baterry Cover and tighten the screw.
NOTE : Using alkaline cell is recommended.
NOTE : Remove the batteries when the clamp meter is out of use for a long
time. The exhausted batteries might leak electrolyte and corrode the
