Instruction manual
4. Preparation for Measurement
4-1 Checking Battery Voltage
Set the function selector switch to any position
other than "OFF". When the display is clear without
"BAT" showing, proceed to measurement. When
the display blanks or "BAT" is indicated, replaces
the batteries according to the instructions described
in section 7 (Battery Replacemen)t.
The sleep feature automatically turns the instrument off in a cer-
tain period of time after the last switch operation. Therefore, the
display may be blank with the function selector switch set to a
position other than "OFF". To operate the instrument in this case,
set the switch back to the "OFF" position, then to the desired
position, or press any switch. If the display still blanks, the
batteries are exhausted. Replace the batteries.
4-2 Checking Switch Setting and Operation
Make sure that the function selector switch is set
to the correct position and the data hold switch is
deactivated. Otherwise, desired measurement
cannot be made.
5.Measurement
5-1 AC Current Measurement
WARNING
!
• Do not make measurement on a circuit with a voltage higher
than 600 VAC. Otherwise, shock hazard or damage to the
instrument or equipment under test may result.
• Transformer jaw tips are designed to minimize the possibility
of shorting conductors in the circuit under test. If equipment
under test has exposed conductive parts, however, extra
precaution should be taken to avoid possible shorting.
• Do not make measurement with the battery compartment
cover removed.
• Do not make current measurement with the test leads
connected to the instrument.
1. Set the function selector switch to the "40Ã" or
"400Ã" position.
2. Press the trigger to open the transformer jaws
and clamp onto one conductor only.
3. Take the reading on the display.
Fig. 2
Correct
NOTE
Incorrect
• During current measurement, keep the transformer jaws fully
closed. Otherwise, accurate measurement cannot be made.
The maxi-mum conductor size is 30 mm in diameter.
• When measuring a larger current, the transformer jaws may
buzz. This does not affect the instrument's accuracy.
5-2 AC Voltage Measurement
• Never use the instrument on a circuit with a voltage higher
than 600 VAC. Otherwise,electric shock hazard or damage to
the instrument or the circuit under test may result.
• Do not make measurement with the battery compartment
cover removed.
1. Set the function selector switch to the "600 ˜ V"
position.
2. Plug the red test lead into the V/Ω terminal and
the black test lead into the COM terminal.
3. Connect the test lead prods to the circuit under
test and take the reading on the display.
5-3 DC Voltage Measurement
• Never use the instrument on a circuit with a voltage higher
than 600VDC. Otherwise,
• electric shock hazard or damage to the instrument or the cir-
cuit under test may result.
• Do not make measurement with the battery compartment
cover removed.
1. Set the function selector switch to the "
position.
2. Plug the red test lead into the V/Ω terminal and
the black test lead into the COM terminal.
3. Connect the test lead prods to the circuit under
test and take the reading on the display.
5-4 Resistance Measurement
• Always make sure that the circuit under test is powered off.
• Do not make measurement with the battery compartment
cover removed.
1. Set the function selector switch to the "Ω/ •
position.
2. Plug the red test lead into the V/Ω terminal and
the black te st lead into the COM terminal.
3. Check that the display reads OL with the test
lead prods shorted together, also check that the
buzzer beeps and the display reads 0.
4. Connect the test lead prods to the circuit under
test and take the reading on the display. The
Fig. 3
buzzer beeps the reading is below 50±35 Ω.
• When shorting the test lead prods together, the display
may show a very small resistance instead of "0". This is the
resistance of the test leads.
• If one of the test leads has an open, the display reads "OL".
