4. Range Selection
4.1 Range Selection
Switching between the 3 mA and 30 mA ranges and between
the 30 A and 60 A ranges is performed by auto-ranging
(automatic).
For switching between the 3/30 mA and 30/60 A ranges,
the range must be switched using the mA/A selector switch.

5. Battery Replacement
5.1 Battery Voltage
If the battery runs down and its voltage falls below the
operating voltage (effective range), the
symbol appears in
the LCD display; promptly replace the battery with a new one.
(Battery: CR2032, 1 piece)
CAUTION
• The specified accuracy is assured when the battery voltage
is in the effective range.
If the
symbol is displayed, promptly replace the battery.
• If the power does not come on even after pressing the
POWER switch, the battery voltage may have fallen too low.
Replace the battery with a new one.
5.2 Replacing the Battery
CAUTION
• Before replacing the battery, always disconnect the tester from
the measurable conductor under test because there is a risk
of electrical shock. After replacement, close the battery cover
securely and conduct measurements.
• Use the specified lithium battery (CR2032).
To replace the battery:
a) Press the POWER switch to turn off the power.
b) Turn the battery cover on the backside of the instrument in
the direction of the arrow using a coin, etc.
c) Remove the cover and the battery.
d) Insert a new battery, making sure that the polarities are
correct.
e) Close the cover back in place by turning it in the reverse
direction of the arrow.

Insert the battery being careful
that the polarities are correct.
Close the battery cover,
aligning the arrow's tail with
the dot and then turn clockwise.

7. Filtering Function
The instrument has a function for turning the filter on (use)/off.
Press the FILTER switch for more than 2 seconds to turn it on/off
(default: ON). When the filter is on, the
symbol appears.
When the FILTER switch is turned on, the sharp filter is enabled.
This filter attenuates 2nd-order and higher harmonic currents and
measures only the fundamental harmonics.
See the Filtering Characteristics below.

■ To Ensure Accurate Measurement
The maximum input current of the harmonic components in
the 3 mA and 30 mA ranges is 150 mA.
If the input exceeds 150 mA, the correct value is not displayed.
In some cases, “0L” does not appear and an error becomes
larger or readings do not change.
Therefore, follow the procedure below to check if the current
under measurement including 2nd-order and higher harmonic
components exceeds 150 mA.
Checking procedure:
1. Press the mA/A selector switch to choose the 30 A range.
2. Press the FILTER switch to select FILTER OFF and conduct
measurement.
3. Check that the measured value (reading) in the 30 A range is
0.15 A* or less.
4. When the measured value is 0.15 A or less, switch the range to
3 mA/30 mA and conduct measurement.
*: The accuracy of the 30 A range is 1.0% of r5 digits
(0.05A < I ≤ 50 A).
Five digits are equivalent to 0.05 A; when checking the current,
also consider the accuracy.
