OPERATION

However, electrical noise or intense electromagnetic fields in the equip­ment may disturb the measurement circuit. Measuring instruments will also
respond to unwanted signals that may be present within the measurement
circuit. Users should exercise care and take appropriate precautions to avoid
misleading results when making measurements in the presence of elec­tronic interference.

Capacitance

1.Dischange capacitors before trying to measure it.

2.Set the Range to the desired C range.

3.Insert the leads directly in to socket or test leads sockets.

4.Never apply an external voltage to sockets damage to the meter may

resuet.

5.Read the capacitance directly from the display.

Note: in lower range 200pF, 2nF subtract residual offset reading from
result with test leads opening.

5

Inductance

1. Set the Ranges to the desired L range.

2. never apply an external voltage to the sockets damage to the meter may

result.

3. Insert the inductor leads derectly into sockets or test leards sockets.

4.Read the inductance directly from the display.

Note:in loues range 200µH, 2mH subtract residual offset reading from

result with test leads being shorted.

Resistance

1. Set the Function/Range switch to the desired resistance range.

2. Remove power from the equipment under test.

3. Connect the red test lead to the

-

" jack.

4. Touch the probes to the test points. In ohms, the value indicated in the

display is the measured value of resistance.

WARNING

The accuracy of the functions might be slightly affected, when exposed

to a radiated electromagnetic field environment, eg, radio, telephone or

similar.

Diode Tests and Continuity Measurements

1. Connect the red test lead to the " + " jack and the black test lead to the

" - " jack.

2. Set the Function/Range switch to the , , microwave , zener

position.

3. Turn off power to the circuit under test.

4. Touch probes to diodes. A forward-voltage drop on diode. microwave diode

about 0.6VDC typical, LED about 2VDC typical, zener diode about its shown

voltage .

5. Reverse probes. if the diode is good, diode, microwave diode. LED about

open voltage 8VDC typical, zener diode about 0.7V typical.

6. If the junction is measured in a circuit and a low reading is obtained with both

lead connections, the junction may be shunted by a resistance of less than

1kW. In this case the diode must be disconnected from the circuit for

accurate testing.

MAINTENANCE

WARNING

Remove test leads before changing battery or fuse

or performing any servicing.

Battery Replacement

Power is supplied by a 9 volt "transistor" battery. (NEDA 1604 IEC 6F22). The
" " appears on the LCD display when replacement is needed. To replace the
battery, remove the two screws from the back of the meter and lift off the
battery case. Remove the battery from battery contacts.

Fuse Replacement

If no capacitance and inductance measurements are possible, check for a
blown overload protection fuse.For access to fuses, remove the two screws
from the back of the meter and lift off the battery case. Replace F1 only with
the original type 0.1A/250V, fast acting fuse.

Cleaning

Periodically wipe the case with a damp cloth and detergent, do not use
abrasives or solvents.
