Inserting/changing the battery The multimeter is powered by a 9V battery. To insert or replace the battery, proceed as follows: Switch off the multimeter and remove all test leads before opening the multimeter! If the battery is exhausted, the icon appears on the display [1]. The battery should be replaced as soon as possible to ensure that the multimeter continues to work properly. Remove the holster [2]. Remove the two screws on the back of the multimeter and remove the back panel. Connect the 9V battery with the correct polarity (note + and –) to the battery clip and place the 9V battery in the battery compartment. Replace the back panel and screw it tight with the two screws. Re-insert the multimeter in the holster [2].POWERFIX PDM 250 A2 English - 79 First use Never exceed the maximum permissible input values. Before measuring, remove the cover of the test probes [7] and the test lead and switch on the multimeter by pressing the on/off button [10]. The multimeter has an auto power OFF function and switches itself off automatically after longer periods of non-use. However, you can also switch off the multimeter directly with the on/off button [10]. You obtain a more accurate measurement result if you use the smallest possible measuring range. Overflow indicator The multimeter has an overflow indicator. If a measured value exceeds the range limit of the selected measuring range, "1" is indicated on the display [1]. In this case, switch to a higher measuring range immediately if possible, or remove the test probes [7] from the test object. DC voltage measurement Connect the black test lead to the COM jack [5] and the red test lead to the V jack [6]. Set the range selector switch [4] to the desired range in the DC voltage measuring range

If you do not know the voltage, first set the highest possible measuring range and then reduce it gradually to the lower ranges until you obtain a satisfactory measurement result. Connect the test probes [7] to the test object. The measurement result is then indicated on the display [1]. A negative sign is indicated in front of the measured value for a negative measurement result. AC voltage measurement Connect the black test lead to the COM jack [5] and the red test lead to the V jack [6]. Set the range selector switch [4] to the desired range in the AC voltage measuring range V

If you do not know the voltage, first set the highest possible measuring range and then reduce it gradually to the lower ranges until you obtain a satisfactory measurement result. Connect the test probes [7] to the test object. The measurement result is then indicated on the display [1].POWERFIX PDM 250 A2

AC current measurement Connect the black test lead to the COM jack [5] and the red test lead to the 10A jack [8] (for currents > 200mA) or to the mA/Ω/BATT jack [9] (for currents < 200mA). Set the range selector switch [4] to the desired range in the AC current measuring range A

If you do not know the current, first set the highest possible measuring range and then reduce it gradually to the lower ranges until you obtain a satisfactory measurement result. Connect the test probes [7] in series to the test object. The measurement result is then indicated on the display [1]. DC current measurement Connect the black test lead to the COM jack [5] and the red test lead to the 10A jack [8] (for currents > 200mA) or to the mA/Ω/BATT jack [9] (for currents < 200mA). Set the range selector switch [4] to the desired range in the DC current measuring range

If you do not know the current, first set the highest possible measuring range and then reduce it gradually to the lower ranges until you obtain a satisfactory measurement result. Connect the test probes [7] in series to the test object. The measurement result is then indicated on the display [1]. A negative sign is indicated in front of the measured value for a negative measurement result. Battery test Connect the black test lead to the COM jack [5] and the red test lead to the mA/Ω/BATT jack [9]. Set the range selector switch [4] to the corresponding battery voltage range 1.5V or 9V in the BATT range. Connect the red test probe [7] to the positive pole and the black test probe [7] to the negative pole of the battery. The measurement result is then indicated on the display [1]. In the measuring ranges BATT 1.5V and BATT 9V, the battery to be measured is charged by an internal resistance, thus you obtain practical information on the condition and functionality of the tested battery.POWERFIX PDM 250 A2 English - 81 Resistance measurement Ensure that all circuit elements, circuits and components to be measured and other test objects are completely switched off and discharged. Otherwise, the multimeter could be damaged. Connect the black test lead to the COM jack [5] and the red test lead to the mA/Ω/BATT jack [9]. Set the range selector switch [4] to the desired range in the Ω measuring range. Connect the test probes [7] to the test object. The measurement result is then indicated on the display [1]. For resistances > 1MΩ, the measurement may take a few seconds. In this case, wait until the measured value has stabilised. The test probes [7] should be handled only behind the finger protection to avoid a distorted measurement result. For measurements of low resistances (200Ω range), the internal resistance of the test leads can lead to a distorted result. To avoid such an error, note the value of the measurement for short-circuited test probes and deduct this from the value of the actual measurement. Continuity test Ensure that all circuit elements, circuits and components to be measured and other test objects are completely switched off and discharged. Otherwise, the multimeter could be damaged. Connect the black test lead to the COM jack [5] and the red test lead to the mA/Ω/BATT jack [9]. Set the range selector switch [4] to the position in the Ω measuring range. Connect the test probes [7] to the test object. If the resistance is less than approximately 60Ω, the buzzer sounds and the measurement result is indicated on the display [1].POWERFIX PDM 250 A2

Diode test Ensure that all circuit elements, circuits and components to be measured and other test objects are completely switched off and discharged. Otherwise, the multimeter could be damaged. Connect the black test lead to the COM jack [5] and the red test lead to the mA/Ω/BATT jack [9]. Set the range selector switch [4] to the position in the Ω measuring range. Connect the red test probe [7] to the anode and the black test probe [7] to the cathode of the diode to be tested. The forward voltage is indicated in volts on the display [1]. If "1" is displayed on the display [1], the diode is measured in the reverse biased-direction or the diode is defective. Perform an opposite pole measurement for check purposes. HOLD function A measured value on the display [1] can be saved by pressing the HOLD button [3]. Press the HOLD button [3] again to return to the measuring mode.POWERFIX PDM 250 A2 English - 83 One-hand operation You can also use the multimeter with one hand.
