Starting Operation
- Never leave the measuring tool unattended when switched on, and ensure the measuring tool is switched off after use.
- Protect the measuring tool from moisture and direct sunlight.
- Do not expose the measuring tool to any extreme temperatures or variations in temperature. For example, do not leave it in a car for extended periods of time. In case of large variations in temperature, allow the measuring tool to adjust to the ambient temperature before putting it into operation. The precision of the measuring tool may be compromised if exposed to extreme temperatures or variations in temperature.
- Avoid substantial knocks to the measuring tool and avoid dropping it.
- Turn the rotation switch (2) to the required measuring function to switch on the Digital Multimeter.
- Turn the rotation switch to the
position to switch off the Digital Multimeter.
If no value is measured for approx. 20 min or no button is pressed on the Digital Multimeter or the rotation switch is not adjusted, the Digital Multimeter will automatically switch itself off to preserve the non-rechargeable batteries. To disable automatic shutdown, press and hold the Hold button while switching on the Digital Multimeter (e.g. by turning the rotation switch to any position). d.APO will then appear in the display. The idle state is always disabled in Min Max Avg mode.
You can then switch the Digital Multimeter back on by turning the rotation switch (2) or pressing one of the buttons.
Sel Button
- Briefly press the Sel button to switch between two measuring functions that have the same position on the rotation switch (2). The respectively selected measuring function is shown on the display (1).
- If the position on the rotation switch is not doubly assigned, an audio signal is output when the Sel button is pressed.
Range Button
- Disconnect the test leads (7) and (8) from the circuit to be tested before adjusting the measuring range. Failure to do so poses a risk of injury from electric shock and/or damage to the Digital Multimeter.
- Briefly press the Range button within the automatic measuring range selection to switch to the manual measuring range selection. Manual is shown on the display (1).
- Briefly press the Range button within the manual measuring range selection to run through various measuring ranges.
- Press and hold the Range button within the manual measuring range selection to switch back to the automatic measuring range selection. Auto is shown again on the display (1).
Min Max Button
- Briefly press the Min Max button to show the minimum, maximum or mid-point values of the measurements. Min, Max or Avg is shown on the display.
Hold Button
"Freezing" a Value on the Display
- Briefly press the Hold button to "freeze" the measured value on the display (1). HOLD is shown on the display and an audio signal is output.
- Briefly press the Hold button again to re-enable the display (1).
Switching Sound Off/On
- Press and hold the Hold button to switch the sound output of the Digital Multimeter off. The
symbol is shown on the display. - Press and hold the Hold button again to switch the sound output of the Digital Multimeter back on.
- Do not use the Hold button when determining the voltage. The voltage displayed does not change and there is a risk of injury due to electric shock.
- Always connect the black test lead (7) to the COM input terminal first, and then connect the red test lead (8) to the V input terminal or the 10 A input terminal. Proceed in reverse when disconnecting the test leads.
- To avoid electric shocks, injuries or damage to the Digital Multimeter before performing resistance, continuity or capacitance tests, ensure that the mains power connection is disconnected and all high-voltage capacitors are discharged.
- Turn the rotation switch (2) to the position in the figure.
- Insert the test lead (8) into the V input terminal.
- Use the test probe to make contact with the 10 A input terminal.
- The measured value is shown on the display (1).
If a value lower than 0.5 Ω is displayed, the fuse is intact.
If 0L is displayed, the fuse (14) is defective and must be replaced see Changing the Fuse.
