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 1000V.

Cautions!

• The maximum rating of your meter is 1000V DC and AC. If you try to measure voltages above 1000V DC or AC, 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 1000V DC/AC with respect to earth/ground. This creates a serious shock hazard.

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.

5.3. Display Symbols

How to make measurements

6.1. Measuring AC/DC voltage

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 appears.

WARNING!
Do not try to measure a voltage greater than 1000V DC or AC. Do not use the rotation knob to switch function with attached voltage.

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.
3. Connect the test leads to the DC/AC voltage source you want to measure.

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 10A terminal is fused. A severe fire hazard and short circuit danger exists if you apply a voltage with high-current capability parallel 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 in series. 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 0,6 A or 10A depending on the terminal used. In the 10A range excessive current flow blows up the fuse, which must be replaced.

1. Set the rotary selector to the desired A range.
2. Use SELECT key to switch between AC or DC measurement
3. Plug the black test lead into your meter’s COM terminal and the red test lead into your meter’s mA or 10A terminal.
4. Connect the test leads in series with the circuit and read the measurement value.

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.

1. Set the rotary selector to the desired OHM function.
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 and read the measurement value.
4. Remove all test leads after the measurement.

Notes:

• When you short the test leads in the 600Ω range, your meter displays a small value (no more than 0.3Ω ). This value is due to your meter’s and test leads internal resistance. Press REL to subtract it from small resistance measurements for better accuracy.
• Always take care of a good connection, as a bad connection influences the resistance measurement.

6.4. Measuring Frequency

Warning! If you try to measure the frequency of a signal that exceeds 250V ACrms, you might damage your meter and expose yourself to a severe shock hazard.
Follow these steps to measure the frequency of a signal:

Note:

• In noisy environments, use shielded cable to measure small signals
• When measuring high voltage circuit, any parts of your body should not touch the high voltage circuit, otherwise it may hurt your body

Note : For the most accurate measurements, we strongly recommend you to use a BNC cable with ferrite core.

1. Set the rotary selector to Hz.
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.

6.5. Capacitance measurements

Warning !
To avoid electric shock, disconnect power to the unit under test and discharge all capacitors before taking any capacitance measurements. To discharge the capacitor, short the pins of the capacitor. Avoid any contact to the pins of a charged capacitor (Danger of electrical shock). The multimeter can be seriously damaged when measuring charged capacitors.

1. Set the function switch to the CAP function.
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 capacitor to be tested. Pay attention to the correct polarity of the capacitor.
4. Read the measurement value. The display will indicate the proper decimal point value.

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-range

2. Insert the temperature pro be to the input sockets V/Ω/Hz (+) and COM (-)

3. Connect temperature probe to measurement object.
   Keep the connection 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.

Warning!

To avoid electric shock, be sure, that the thermocouple has been removed before changing to another measurement function.

6.7. 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.

1. Set the rotary selector to the diode position.
2. Press select key until diode symbol is shown
3. Plug the black test lead into your meter’s COM terminal and the red test lead into the V/Ω/Hz/- terminal.
4. Connect the test leads to the diode and the reading is displayed

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 over range, the diode is good. The displayed number is the diode’s actual forward voltage (up to 2.0V).
• If the display indicates an over range 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.V). If the display still indicates an over range condition, the device is open.
• If the display shows a value both before and after you reverse the polarity, the device is shorted.
