5-3 Current Measurement (ACA)
Remove the test leads from the measuring
terminals to avoid electric shock.
Remarks:
·
Clamp the conductor (cable) to measure at the
center of the trans core (CT).
·
Clamp only one cable. If several cables are
clamped together or 2 core or 3 core cords or
cables are clamped, current cannot be
measured accurately.
·
The meter may malfunction in places where a
strong magnetic field is present.
5-4 Voltage Measurement (ACV DCV)
Never use the meter in power lines exceeding
600 V to ground.
5-5 Resistance Measurement, Continuity
Check
Never apply a voltage to the input terminals.
Remarks
·
Reading is 30 ohm or below, buzzer sounds.

[6] MAINTENANCE
1.The following instructions are very important for
safety. Read this manual thoroughly to ensure
correct maintenance.
2.Calibrate and inspect the meter at least once a
year to ensure safety and maintain its accuracy.
6-1 Maintenance and Inspection
1) Appearance: Is the meter not damaged due to
falling or other cause?
2) Test leads:
Are the core wires not exposed from the
test leads?
Is the plug when inserted to the input
terminal not loose?
If any of the above problems exists, stop using
the meter and request for repair.
6-2 Calibration and Inspection
For more information, please contact Sanwa
s
authorized agent / distributor service provider,
listed in our website. See section 7 3.
6-3 Storage
1. The panel and case are not resistant to
volatile solvent and must not be cleaned with
thinner or alcohol.
2. The panel and case are not resistant to heat.
Do not place the meter near heat generating
devices.
3. Do not store the meter in a place where it
may be subjected to vibration or from where it
may fall.
4. Do not store the meter in places under direct
sunlight, or hot, cold or humid places or
places where condensation is anticipated.
5. If the meter will not be used for a long time,
remove the batteries.
6-4 Battery Replacement
Batteries when the meter is shipped:
A battery for monitoring has been installed prior to
shipment from the factory. It may be discharged
before the expiration of the described battery life.
*The battery for monitoring is a battery used to
check the functions and performance of the
product.
To avoid electric shock, do not remove the battery
door with an input being applied to the measuring
terminals. Also, before starting replacement, make
sure the power of the meter is OFF.
1. Remove the fixing screw of the battery lid with
a minus screwdriver.
2. Replace both two batteries in the battery
holder with new ones. (Pay attention to their
polarity.)
3. Set and secure the battery door with the fixing
screw as before.

Note:
1) Prior to requesting repair, please check the
following: Capacity of the built in battery,
polarity of installation and discontinuity of the
test leads.
2) Repair during the warranty period: The failed
IEC61326
Instruction manual
Test leads (TL 23a)
EMC Directive:
Standard
Accessories:
meter will be repaired in accordance with the
conditions stipulated in 7 1 Warranty and
Provision.
3) Repair after the warranty period has expired: In
some cases, repair and transportation cost
may become higher than the price of the
