To avoid possible electric shock or personal injury, follow theseguidelines:

Do not use the meter if it is damaged. Before you use the meter, inspect the case. Pay particular attention to the insulation surrounding the connectors. Inspect the test leads for damaged insulation or exposed metal.

Check the test leads for continuity. Replace damaged test leads before you use the meter. Do not use the meter if it operates abnormally. Protection may be

impaired. When in doubt, have the meter serviced. Do not operate the meter around explosive gas, vapor, or dust. Do not apply a voltage or current higher than the selected range's

upper limit between terminals. Before use, verify the meter's operation by measuring a known

voltage. When measuring dc current, turn off power to the circuit before

connecting the meter to the circuit. Remember to place the meter in series with the circuit. When servicing the meter, use only specified replacement parts. Use caution when working with voltage above 30V ac rms, 42V

Warning

SAFETY INFORMATIONThe meter has been designed according to IEC-61010 concerningelectronic measuring instruments with a measurement category III(CAT III 500V) and Pollution degree 2.

peak, or 60V dc. Such voltages pose a shock hazard. When using the probes, keep your fingers behind the finger

guards on the probes. Connect the black test lead before you connect the red test lead.

When you disconnect test leads, disconnect the red test lead first. Remove the test leads from the meter and remove the clamp jaws

from any clamped object before you open the battery cover or the case. Do not operate the meter with the battery cover or portion of the

case removed or loosened. To avoid electric shock, do not touch any naked conductor with

hand or skin and do not ground yourself. Adhere to local and national safety codes. Individual protective

equipment must be used to prevent shock and arc blast injury where hazardous live conductors are exposed. Do not hold the meter anywhere beyond the tactile barrier. Do not use the test leads with other equipment. Remaining endangerment:

When an input terminal is connected to dangerous live potential it is to be noted that this potential can occur at all other terminals! CAT III - Measurement Category III is for measurements

performed in the building installation. Examples are measurements on distribution boards, circuit breakers, wiring, including cables, bus-bars, junction boxes, switches, socket outlets in the fixed installation, and equipment for industrial use and some other equipment, for example, stationary motors with permanent connection to the fixed installation. Do not use the meter for measurements within Measurement Categories IV.

CautionTo avoid possible damage to the meter or to the equipment undertest, follow these guidelines:

Disconnect circuit power and discharge all capacitors before measuring resistance or temperature. Use the proper function and range for your measurements. Before measuring dc current, turn off power to the circuit before

connecting the meter to the circuit. Before rotating the rotary switch to change functions, disconnect

test leads from the circuit under test and remove the clamp jaws from any clamped object.

OPERATION INSTRUCTION

Preparation for Measurements

Use a small flat tip screwdriver to adjust the Pointer Zero Correctoruntil the pointer is directly over the zero at the left end of the scale A( or scale B ).

10

1. Connect the black test lead to the " COM " terminal and the red test lead to the " V mA " terminal.2. Set the range switch to ×1 or ×100 position.3. Turn the 0 adjuster knob to set the pointer to the " 0 " position of the scale C while shorting the test leads. Note: If the pointer can't be adjusted to the " 0 " position of the the scale C, replace the batteries.4. Make sure that the object to be tested is without power.5. Connect the test leads across the object and read the scale C referring the reference table.

1. Connect the black test lead to the " COM " terminal and the red test lead to the " V mA " terminal.2. Set the range switch to the desired range position. If the magnitude of the voltage to be measured is not known beforehand, set the range switch to the highest range position first and then reduce it range by range if necessary.3. Connect the red test lead to the positive terminal of the circuit to be tested and the black one to the negative terminal of the circuit. Note: If the pointer deflects to the left of the scale B, reverse the test leads.4. Read the scale B referring the reference table.

b. The wire should be in the center of the jaws in order to get an accurate reading.3. Read the scale A referring the reference table.

Note:1. For measurements > 400A, measurement duration must not exceed 30 secs and interval between measurements should be more than 5 minutes.2. When you measure large current, the jaws may emit a faint sound at their joint. This is normal and does not affect measurement accuracy.

1. Set the range switch to the ×100 ( Temp. ) position.2. Connect the black test lead to the " COM " terminal and the red test lead to the " V mA " terminal. Short the two test leads together and adjust the 0 adjuster knob until the pointer is directly over the " CAL " scale mark on the scale D.3. Remove the test leads. Then insert the black plug of the Temperature Probe into the " COM " terminal and the red plug of the Temperature Probe into the " V mA " terminal.4. Touch the probe tip of the Temperature Probe to the object to be measured, read scale D when they reach thermal equilibrium.

Note:1. Do not make measurement on any live conductor.2. To avoid heat injury, do not touch hot probe with hand or skin.2. Do not measure any object whose temperature exceeds 150°C.

BATTERY AND FUSE REPLACEMENTConnect the black test lead to the " COM " terminal and the red testlead to the " V mA " terminal. If the pointer can not be set to " 0 "position of the scale C by turning the 0 adjuster knob while therange switch is in ×1 or ×100 position and the test leads are beingshorted, the batteries are low and should be replaced.

To replace batteries, remove the screw on the battery cover andremove the battery cover, replace the exhausted batteries with newbatteries of the same type ( 1.5V battery, AAA or equivalent ), makesure that the polarity connections are correct. Reinstall the batterycover and the screw.

If the meter can not work, you should replace the fuse.To replace fuse, remove the screw on the battery cover and removethe battery cover, then remove the screws on the back cover andremove the back cover, replace the blown fuse with a new one of thesame ratings. Reinstall the back cover, the battery cover and all thescrews.

The meter uses one fuse: 250mA/500V, FAST, Ø6.35X32mm
