the jaw is locked before making measurements.
• Have an approved technician repair the Product.
Caution
• For best accuracy please consider following impacts:
- use whenever possible optimized position of the
clamp when the conductor is positioned is in the center
of jaw and the angle between conductor and jaw is 90°
- reduce influences by external magnetic field
(for impact see error E11 in specification table)
- reduce influences by contamination of the jaw
(recommendation for cleaning see in chapter
maintenance)
• The measurement of differential current will be
influenced by the load current (for influence of load
current, see error E12 in Specification table).

• If the Product is used in the vicinity of equipment that
generates electromagnetic interference, the display
may become unstable or the measurements shown may
be subject to large errors.
• Do not subject the jaw to unreasonably strong shock,
vibration or force.
• If dust gets into the top of the jaw, remove it
immediately. Do not close the jaw when dust is trapped
in its joints as the sensor may be damaged.

LEAKAGE CURRENT MEASUREMENT
The leakage current flows when an unintentional electrical
connection occurs between an energized part of the
electrical system and the earth/ground. The desired value of
leakage current should be 0A. Check applicable regulations
and standards for allowable limits of leakage current.
For properly grounded systems, in case of the fault,
leakage current should be conducted via earth conductor
(PE) (Figure 1). We can measure such current directly in a
earth conductor using a leakage clamp meter.
In some cases, specifically when equipment is not properly
grounded, the leakage current may flow through other
paths. Use differential current measurement methods
to verify such current leaks (Figure 2, Figure 3, Figure 4).
Clamp a leakage current meter around all active conductors
(hot and neutrals), but without any earth conductor. An
electromagnetic field around all conductors should cancel
each other if there is no current leak and clamp meter
should read 0A. If there is a leak, there will be imbalance
between electromagnetic fields, and the clamp meter will
read the actual value of that leakage current.
Leakage current measurement process
1. Turn the meter on.
2. Make sure the jaw is closed and the meter is away from
conductors and other sources of electromagnetic fields.
3. Clamp the meter around a earth conductor. The meter
will indicate leakage current in earth conductor.
4. Clamp the meter around all active conductors, hot and
neutrals (but without earth conductors). The meter
will indicate total system leakage current that consists
of earth conductor current as well as any other stray
current leakage.

LOW PASS FILTER (50-60 HZ) & APPLIANCE FILTER
Low Pass and Appliance filters are used to filter out high
frequency noise that affect precise measurement of the meter.
• Use Low Pass 50/60Hz filter to perform measurements on
equipment driven by Variable Frequency Drives (VFDs) or
affected by high frequency noise. Significant difference
in reading between measurement with and without low
pass filter may indicate presence of harmonics.
• Use Appliance Filter to conduct leakage current
measurements of appliances in accordance with
IEC/EN 61557-16 regulation requirements.

LIMIT
Limit selection:
The LIMIT function offers 5 limit values (3.5 mA / 10 mA / 12 mA /
0.25 mA / 0.5 mA) in accordance with safety standards.
1. Continue pressing LIMIT button until desired limit value
is selected. The unit will be looping between 3.5 mA /
10 mA / 12 mA / 0.25 mA / 0.5 mA values.
2. When desired value is selected wait 2 sec to automatically
apply selection. The LIMIT symbol will be displayed on the
LCD to indicate that the function is active.
3. Verify the selection by pressing the LIMIT button one
time. The unit will display the selected value for 2 seconds.
4. To disable the LIMIT function, press the LIMIT button for
>2 sec.
Display when limit is exceeded:
The internal buzzer will continue beeping and the
display will flash and show a warning symbol when the
measurements exceeds the selected limit value.
