5. Preparation for Operation
5.1. Using the test leads
Use only the identical type of test leads supplied with your
meter. These test leads are rated for 1200 V.
Cautions!
* Although the replacement probes are rated for 1200 V, the
maximum rating of your meter is 1000 V DC and 750 V AC. If
you try to measure DC voltages above 1000 V or AC voltages
750 Vrms, you might damage your meter and expose yourself
to a serious shock hazard. Use extreme care when you
measure high voltages.
* Never connect the probe you plug into the COM terminal to a
source of voltage greater than 1000 V DC/750 V ACrms with
respect to earth/ground. This creates a serious shock hazard.
-40-
5.2. Using the stand
Use your meter’s stand to prop up the meter. If you prop your
meter on a bench-top, the stand helps provide a better viewing
angle.
To use the stand as a prop, just open it away from the meter and
set it on a flat surface.
6. How to make measurements
Understanding Phantom readings:
In some DC and AC voltage ranges, when the test leads are not
connected to any circuit, the display might show a phantom
reading. This is normal. The meter’s high input sensitivity
produces a wandering effect. When you connect the test leads
to a circuit, accurate reading appear.
6.1. Measuring AC/DC voltage
WARNING!
Do not try to measure a voltage greater than 1000 V DC or
750 V AC. You might damage your meter and expose yourself to
a severe shock hazard.
Follow these steps to measure DC/AC Voltage.
1. Set the rotary selector to the desired position. Select the
range as required for the voltage level to be measured. If
you do not know the voltage level, start with the range switch
set to the highest voltage position and reduce the setting as
needed to get a reading.
2. Plug the black test lead into the meter’s COM terminal and
the red test lead into the V/Ω/Hz-terminal.
-41-
3. Connect the test leads to the DC/AC voltage source you
want to measure.
Warning! When you connect the test probes to an AC outlet, do
not turn the rotary selector switch to another range. It could
damage the meter’s internal components or injure you.
6.2. Measuring DC/AC Current
WARNING!
* Do not apply voltage directly across the terminals. You must
connect the meter in series with the circuit.
* The 10 A terminal is fused. A severe fire hazard and short
circuit danger exists if you apply a voltage with high-current
capability to this terminal. The meter can be destroyed under
such conditions.
To measure current, break the circuit and connect the probes to
two circuit connection points. Never connect the probes across a
voltage source in parallel. Doing so can blow the fuse or damage
the circuit under test.
Note:
The maximum input current is 200 mA or 10 A depending on the
terminal used. In these ranges excessive current blows the
fuses, which you must replace.
1. Set the rotary selector to the desired A range. If you do not
know the current level, set it to the highest position and
reduce the setting as needed to get a reading.
2. Plug the black test lead into your meter’s COM terminal and
the red test lead into your meter’s mA or 10 A terminal.
-42-
3. Remove power from the circuit under test and then break
thecircuit at the appropriate point.
4. Connect the test leads in series with the circuit.
5. Apply power and read the current. Your meter displays the
current value.
Note:
If you see the meter for DC current, “-” appears or disappears.
This indicates the polarity of the measured current.
6.3. Measuring Resistance
WARNING!
* Never connect the test leads to a source of voltage when
you have the selected the OHMS function and plugged the
test leads into the V/Ω/Hz-terminal.
*
Be sure that the circuit under test has all power removed
and that any associated capacitors are fully discharged
before you make a resistance measurement.
The resistance measuring circuit compares the voltage gained
through a known resistance (internal) with the voltage developed
across the unknown resistance. So, when you check in-circuit
resistance, be sure the circuit under test has all power removed
(all capacitors are fully discharged).
1. Set the rotary selector to the desired OHM range.
2. Plug the black test lead into your meter’s COM terminal and
the red test lead into your meter’s V/Ω/Hz-terminal.
3. Connect the test leads to the device you want to measure.
-43-
Notes:
* If the measured resistance value exceeds the maximum
value of the range selected, 1 appears flashes. This
indicates an overload. Select a higher range. In this mode,
the beeper does not sound.
* When you short the test leads in the 200 Ω range, your
meter displays a small value (no more than 0.3 Ω). This
value is due to your meter’s and test leads internal
resistance. Make a note of this value and subtract it from
small resistance measurements for better accuracy.
6.4. Capacitance measurements
Warning !
To avoid electric shock, disconnect power to the unit under test
and discharge all capacitors before taking any capacitance
measurements. Remove the batteries and unplug the line cords.
1. Set the function switch to the CAP position.
2. Press the LC-button
3. Plug the black test lead into your meter’s V/Ω/Hz- terminal
and the red test lead into your meter’s mA-terminal.
4. Touch the test leads to the capacitor to be tested. The
display will indicate the proper decimal point value.
6.5. Inductance measurements
1. Switch to a proper range and insert test leads into “mA” and
“V/Ω/Hz” jack.
2. Press LC-button
3. Connect the test leads crossly to the two ends of inductor.
-44-
Notes:
1. If inductance exceeds the range selected. “OL” will be
displayed on LCD, the you shall increase the range by on
step.
2. The inductance value measured for identical inductor may
be different if there is different impendence.
3. If in range 2 mH, please short test leads and measure lead
inductance and then subtract the inductance from the value
measured.
4. Avoid measuring small inductor in high range, or the
accuracy is not guaranteed.
6.6. Temperature measurements
Warning!
To avoid electric shock, disconnect both test probes from any
source of voltage before making a temperature measurement.
1. If you wish to measure temperature set the function switch to
the °C- or °F-range
2. Insert the temperature-adaptor to the input sockets mA (+)
and V/Ω/Hz (-)
3. Touch the Temperature probe head to the part whose
temperature you wish to measure. Keep the probe touching
the part under test until the reading stabilizes (about
30 seconds).
4. Read the temperature in the display. The digital reading
will indicate the proper decimal point and value.
-45-
Warning!
To avoid electric shock, be sure, that the thermocouple has been
removed before changing to another measurement function.
6.7. Measuring Frequency
Warning! If you try to measure the frequency of a signal that
exceeds 500 V ACrms, you might damage your meter and
expose yourself to a severe shock hazard.
Follow these steps to measure the frequency of a signal:
1. Set the rotary selector to 10 MHz.
2. Plug the black test lead into your meter’s COM terminal and
the red test lead into you meter’s V/Ω/Hz-terminal.
3. Connect the test leads to the frequency source.
Warning!
When you connect the test leads to an AC outlet, do not turn the
function rotary selector to another range. It could damage the
meter’s internal components or injure you.
Note:
For the most accurate measurements, we strongly recommend
you to use a BNC cable with ferrite core.
6.8. Checking diodes
This function lets you check diodes and other semiconductors
for opens and shorts. It also lets you determine the forward
voltage for diodes. You can use this function when you need to
match diodes.
1. Set the rotary selector to the diode position.
-46-
2. Plug the black test lead into your meter’s COM terminal and
the red test lead into your meter’s V/Ω/Hz/-terminal.
3. Connect the test leads to the diode you want to check and
note the meter reading.
Notes:
* If the display shows a value for example 0.2 for a
germanium diode or 0.5 for a silicon diode, reverse the
diode. If the meter indicates and overrange, the diode is
good. The displayed number is the diode’s actual forward
voltage (up to 2.0 volts).
* If the display indicates an overrange condition, reverse the
polarity of the connection. If the display shows a value, the
device is good. The displayed value is the component’s
actual forward voltage (up to 2.0 volts). If the display still
indicates an overrange condition, the device is open.
* If the display shows a value both before and after you reverse the polarity, the device is shorted.
When you connect the diode to the meter and the meter displays
the devices forward voltage, the red test lead is connect to the
diods’s anode, and the black test lead is connected to the
diode’s cathode. This meter supplies enough forward voltage to
light most LED´s. However, if the LED’s forward voltage is
greater than 2.0 volts, the meter incorrectly indicates that the
device is open.
6.9. Checking Continuity
Follow these steps to check a circuit’s continuity.
1. Set the rotary selector to
2. Plug the black test lead into your meter’s COM terminal and
the red test lead into your meter’s V/Ω/Hz/-terminal.
-47-
3. Remove power from the circuit.
4. Connect the test leads to the circuit.
Note:
The buzzer sounds if the measured resistance is below about
70 Ω approximately.
Warning!
Never perform a continuity measurement on a circuit that has
power connected.
6.10. Transistor hFE
1. Turn the range switch to “hFE” position.
2. Insert test leads into “mA” and “com” jack. Please pay
attention to the polarity, as the “Com” for positive and “mA”
