6 Measuring

WARNING

Measurements in circuits carrying more than 42 V must only be made by persons able to recognize a hazard of contact and to take the required safety precautions. In case of measurements with a hazard of contact, avoid working on your own. Ask a second person to assist.

Caution: Before switching to another measuring function, always remove the test tips from the object to be measured to prevent damage to the meter!

6.1 Measuring voltages

WARNING

Take into account unexpected voltages on objects to be measured. Capacitors, for example, may be dangerously charged even if the voltage source has been switched off.

• Never use this meter for measuring circuits with corona discharges (high voltage). Risk of electrocution!
• The maximum voltage to be measured must not exceed 1000 V=\~/\~, otherwise you will risk your life!

Caution: Connect the red test lead to the jack "V Hz Ω CAP °C °F" (11). If it is connected to the jack "10A" (4) or "μA/mA" (5), the meter and the object to be measured may be damaged!

1) Set the selector switch (10) to the position "V≡" to activate the mode "DC voltage measurement" ("DC" will be displayed).
2) For AC voltage measurements, press the button "MODE" (3) ["AC" will be displayed]. To return to "DC", press the button "MODE" again.
3) Apply the test tips to the object to be measured and read the value on the display. If the red test tip is applied to the negative pole and the black tip to the positive pole when measuring DC voltages, there will be a minus sign in front of the value displayed.

6.2 Measuring currents

- The current to be measured must not exceed 10 A!

1) For measurements up to 400 mA, connect the red test lead to the jack “ A/mA” (5); for measurements up to 10 A, connect it to the jack “10A” (4). With unknown currents, start with the 10 A range to be on the safe side.
2) According to the intensity of current, set the selector switch (10) to the following position: up to 4000 μA position “μA” ≈

4000 μA to 400 mA position “mA” ≈ 400 mA to 10 A position “10A” ≈

The mode “DC current measurement” will be activated (“DC” will be displayed).

3) For AC current measurements, press the button "MODE" (3) ["AC" will be displayed].

To return to "DC", press the button "MODE" again.

4) Insert the meter via the test leads into the circuit to be measured and read the value on the display. If the red test tip is applied to the negative pole and the black tip to the positive pole when measuring DC currents, there will be a minus sign in front of the value displayed.

If the current measured exceeds the admissible value of a measuring range, warning signals will sound and "OL" (overload) will be displayed. In this case, select the next higher range.

6.3 Measuring resistances

- Never measure a resistor when voltage is applied; always measure it separately, otherwise the measurement will be inaccurate. For this purpose, it may be necessary to solder it out of the circuit.

1) Set the selector switch (10) to the position "Ω → to activate the mode "resistance measurement".
2) Apply the test tips to the resistor and read the value on the display. As long as the resistance value between the test tips is >40 MΩ, “OL” will be displayed to indicate that the measuring range has been exceeded.

6.4 Testing the continuity

- Never test the continuity when voltage is applied, otherwise the measurement will be inaccurate.

The continuity buzzer will help to detect interruptions in the circuit.

1) Set the selector switch (10) to the position "Ω # to activate the mode "resistance measurement".
2) To switch to continuity test, press the button "MODE" (3) once (buzzer symbol will be displayed).
3) Apply the test tips to the measuring points. If the resistance value between the points is smaller than 35 , the internal buzzer will sound. The resistance value will be displayed up to 400 . With higher values, the overload indication “OL” will appear.

6.5 Testing diodes

- Never test a diode when voltage is applied; always test it separately, otherwise the measurement will be inaccurate. For this purpose, it may be necessary to solder the diode out of the circuit.

1) Set the selector switch (10) to the position "Ω → to activate the mode "resistance measurement".
2) To switch to diode test, press the button "MODE" (3) twice (diode symbol will be displayed).
3) Apply the black test tip to the cathode of the diode and the red test tip to the anode. With a measurement current of approx. 1 mA, a forward voltage up to 1.999 V will be displayed. If a value around 0 V is displayed, the diode has a short circuit. If “OL” is displayed, the diode is interrupted, reverse-biased (reverse the polarity of the diode) or has a higher forward voltage (e.g. some LEDs).

6.6 Measuring capacitances

WARNING

Never measure a capacitor when it is charged or when operating voltage is applied; otherwise you will risk an electric shock.

Switch off the power supply and discharge the capacitor before soldering it out of the circuit.

1) Set the selector switch (10) to the position "CAP".
2) Apply the test tips to the capacitor. With electrolytic capacitors, observe the polarity: Apply the red test tip to the positive pole, apply the black test tip to the negative pole.

Read the value on the display. With very high capacitances, the measuring process will require some time. It may take a few minutes before the reading on the display has stabilized. When measuring capacitances, the bar graph will have no function.

Note: If the display shows “diS.C”, the capacitor is charged and must be discharged before measuring. Due to the long discharge time, it is not recommended to discharge the capacitor via the multimeter.

6.7 Measuring frequencies

1) Set the selector switch (10) to the position "Hz".
2) Apply the test tips to the measuring points like for measuring voltages.
3) Read the frequency on the display.

6.8 Measuring temperatures

For measuring the surface temperature of objects, the meter is supplied with a type K temperature sensor with banana adapter plug. The temperature measurement is not suitable for medical purposes!

WARNING

To avoid electric shock, do not apply the temperature sensor to any objects carrying voltage.

1) Connect the sensor to the multimeter via the adapter plug: Connect the positive pole to the jack "V Hz Ω CAP °C °F" (11) and the negative pole to the jack "COM" (12).
To ensure protection of the meter according to IP 67 (e.g. to protect it against humidity for outdoor applications), insert the sleeves (13) provided into the two red jacks not used.
2) Set the selector switch (10) to the position “°C • °F”. After switching on, the mode “Fahrenheit” will be activated (“°F” will be displayed).
3) To switch to Celsius, press the button "MODE" (3) ["°C" will be displayed]. To return to "°F", press the button "MODE" again.
4) Apply the sensor to the object to be measured.
5) Once the reading has stabilized (after approx. 30 seconds), read the temperature on the display.

7 Additional Functions

7.1 Manual range selection

The optimum range for a measuring function will always be selected automatically when "AUTO" is displayed.

1) To hold a range selected automatically, press the button "RANGE" (1). "AUTO" will disappear and "MANU" will appear.

2) Each time the button "RANGE" is pressed, the next higher range will be selected. This will reduce the resolution of the measured value, but it will prevent permanent switching if the measured value fluctuates between two ranges.

When the highest possible range has been reached and the button is pressed again, the smallest range will be selected. If the range is too small, "OL" (overload) will be displayed. When measuring voltages and currents, warning signals will sound additionally.

3) To return to automatic range selection, keep the button "RANGE" pressed for approx. 2 seconds until "AUTO" appears instead of "MANU".

7.2 Data hold function

To hold a measured value on the display (e.g. to be able to read the value more easily when the test tips have been removed from the object to be measured), press the button "HOLD" (2). The digital display will hold the measured value, "HOLD" will appear and the automatic range selection will be deactivated ("MANU" will be displayed).

To deactivate the data hold function, press the button "HOLD". "HOLD" will disappear and the automatic range selection will be reactivated ("AUTO" will be displayed).

7.3 Indicating the maximum/minimum value

With the MAX/MIN function activated, the meter will record the maximum value and minimum value of a measurement and indicate them on the display. To activate this function, press the button "MAX / MIN" (8). The automatic range selection will be deactivated ("MANU" will be displayed). The button "MAX/MIN" will allow to switch between three indications:

1. "MAX": The digital display will show the maximum value measured since the function has been activated. If a higher value is reached while measuring, the indication will be updated accordingly.
2. "MIN": The digital display will show the minimum value measured since the function has been activated. If a lower value is

reached while measuring, the indication will be updated accordingly.

1. "MAX/MIN" (flashing): The digital display will show the present reading.

To deactivate this function, keep the button "MAX/MIN" pressed for approx. 2 seconds. The automatic range selection will be reactivated ("AUTO" will be displayed).

To reset the values in order to perform a new MIN/MAX measurement, deactivate and reactivate the function.

7.4 Indicating short peaks

When measuring voltages (=/\~) and currents (=/\~), the PEAK function will allow to indicate peak values occurring too shortly to be recorded during the MAX/MIN measurement (chapter 7.3), e.g. short interfering pulses. It will be possible to measure peaks of a duration ≥ 1 ms.

1) When measuring voltages or currents, wait until the reading on the display has stabilized.
2) Keep the button "PEAK" (7) pressed until "CAL." is displayed: A calibration will be performed.
3) After calibrating, press the button "PEAK". The digital display will indicate the positive peak value of the measurement ("PMAX"). The automatic range selection will be deactivated ("MANU" will be displayed).

When the button “PEAK” is pressed again, the indication will change to the negative peak value of the measurement (“PMIN”).

If a higher or lower peak value is reached while measuring, the corresponding indication will be updated.

4) Use the button "PEAK" to switch between "PMAX" and "PMIN".
5) To deactivate this function, keep the button pressed for approx. 2 seconds until "PMAX" or "PMIN" disappears. The automatic range selection will be reactivated ("AUTO" will be displayed).

Note: If you select another measuring function with the selector switch (10) after calibrating, repeat the calibration for the new measuring function.
