SAFETY INFORMATION
The following safety information must be observed to ensure maximum personal
safety during the operation at this meter:
Use the meter only as specified in this manual or the protection provided by the
meter might be impaired.
Test the meter on a known voltage before using it to determine if hazardous
voltage is present.
Do not use the meter if the meter or test leads look damaged, or if you suspect
that the meter is not operating properly.
Never ground yourself when taking electrical measurements. Do not touch
exposed metal pipes, outlets, fixtures, etc., which might be at ground potential.
Keep your body isolated from ground by using dry clothing, rubber shoes, rubber
mats, or any approved insulating material.
Turn off power to the circuit under test before cutting, unsoldering, or breaking
the circuit. Small amounts of current can be dangerous.
Use caution when working above 60V dc or 30V ac rms. Such voltages pose a
shock hazard.
When Using the probes, keep your fingers behind the finger guards on the
probes.
Measuring voltage which exceeds the limits of the multimeter may damage the
meter and expose the operator to a shock hazard. Always recognize the meter
voltage limits as stated on the front of the meter.

OPERATION
Before taking any measurements, read the Safety Information Section. Always
examine the instrument for damage, contamination (excessive dirt, grease, etc.)
and defects. Examine the test leads for cracked or frayed insulation. If any
abnormal conditions exist do not attempt to make any measurements.
Voltage Measurements
1.Connect the red test lead to ”VΩ ” jack and the black test lead to the ”COM”
2.Set the Function/Range switch to the desired voltage type (AC or DC) and
3.Connect the test leads to the device or circuit being measured.
4. For dc, a (-) sign is displayed for negative polarity; positive polarity is implied.
Current Measurements
1.Connect the red test lead to the (uA, mA or 10A) jack and the black test lead to
2.Set the Function/Range switch to the DC or AC ranges.
3.Remove power from the circuit under test and open the normal circuit path
4.Apply power and read the value from the display.
Resistance and Continuity Measurements
1.Set the Function/Range switch to the desired resistance range or continuity
2.Remove power from the equipment under test.
3.Connect the red test lead to the “ VΩ” jack and the black test lead to
4.Touch the probes to the test points. In ohms, the value indicated in the display
Diode Tests
1.Connect the red test lead to the “ VΩ” jack and the black test lead to
2.Set the Function/Range switch to the “
3.Turn off power to the circuit under test. External voltage across the
components causes invalid readings.
4.Touch probes to the diode. A forward-voltage drop is about 0.6V (typical for a
5.Reverse probes. If the diode is good, “OL” is displayed. If the diode is shorted,
6. If the diode is open, “OL” is displayed in both directions.
Battery Test
1. Connect the red test lead to the (mA/BATT 1.5V) jack and the black test lead to
2. Set the Function/Range switch to the desired 1.5V battery test range.
3. Connect the test leads to the 1.5Vdc battery under test. Normally, a good

Fuse Replacement
If no current measurements are possible. check for a blown overload protection
fuse. For access to fuses, remove the three screws from the back of the meter
and lift off the front case. Replace F1 only with the original type 0.5A/500V, fast
acting ceramic fuse, 6.35x32mm .
Replace F2 only with the original type 10A/600V, fast acting ceramic fuse,
6.35x25.4mm.
Cleaning
Wipe the case with a damp cloth and mild detergent. Do not use abrosives or
solvents. Dirt or moisture in the terminals can affect readings.
