CAUTION

• Before o perating this instrument, familiarize yourself with al l instructions outlined in this manual.
• Always check to make sure that the function switch is set to the proper position.
• When making measurements, use CAUTION as dangerous voltages ma y be present in normally safe areas.
• To avoid electrical shock, use CA UTION when working above 60V DC or 25V AC rms. Such voltages pose a shock hazard.
• Never make measurements with the battery cover OFF.
• Never fail to keep the maximum tolerable input.
• N ever operate this instrument if it becomes wet, damp or has any liquid condensation build up on any part of the instrument.
• Never make measurements for uninsulated conductors or bus bars.

5. METHOD OF MEASUREMENT

5-1 Preparation and Caution before Measurement

• Before making measurement, install the batteries. (Two LR-44 or SR-44)
• Avoid using the tester in places subject to high temperature, humidity or excessive vibration.
• Do not use or store the tester in an area subject to magnetic fields or electric noises. Unstable reading and measurement error may result.
• Before measurement, be sure the data hold switch is set to “OFF”. It is impossible to make measurement if the data hold switch is set to “ON”.
• Remove the batteries, if the tester will not be used for a long period.

5-2 AC Current Measurement

1. Set the power switch to “ON” position.
2. Set the range selector switch to appropriate range to the current to be measured.
3. Clamp the conductor of the circuit under test with current transducer.

Note: Clamp around only one conductor in the circuit to be measured.

1. Read the displayed value.
2. If you make measurement in a dark place or in a place where it is difficult to see the readings, use the data hold switch.
3. After measurement, set the power switch to “OFF”

CAUTION:

This tester is designed for low voltage applications.
To avoid electrical shock or damage, the measurement is limited to the circuit under 600V AC.

6. REPLACEMENT OF BATTERIES

When the battery becomes exhausted or drops below the operating voltage, the “B” mark is displayed. Turn the power switch to “OFF”, prior to installing batteries.
To install the batteries, remove the battery cover located on the unit back. (See Fig.2) Insert the two LR-44 or SR-44 into the battery case making sure that proper polarity is observed. (See Fig.3)
Always replace both batteries at the same time. If the difference between the voltages of the batteries is big, the measurement error may be caused.
