Function/Application

Current and voltage multimeter for taking measurements in the range of overvoltage category CAT III up to max. 600V. The meter can be used to measure DC and AC voltages and direct and alternating currents, resistance and for continuity tests within the specified ranges. Furthermore, the device features a PEAK function, a MAX/MIN display, a hold function and a True RMS measurement (Root-Mean-Square) function. The device is also equipped with a torch and an illuminated display.

Safety instructions

• The device must only be used in accordance with its intended purpose and within the scope of the specifications.
• Before taking any measurements, make sure that both the area to be tested (e.g. a line), the test device and the accessories used (e.g. connection cable) are in proper working order. Test the device by connecting it to known voltage sources (e.g. a 230 V socket in the case of AC testing or a car battery in the case of DC testing). Stop using the device if one or a number of its functions fails.
• If you are working with voltages higher than 25 V AC/60 V DC, exercise extreme caution. Touching the electrical conductors at such voltages poses a risk of life-threatening electric shocks.
• Make sure that you always select the correct connections, the correct rotary switch position and the correct range for the measurement to be taken.
• Before measuring or checking the resistance, continuity, diodes or capacitance, disconnect the power supply to the electric circuit. Check that all high-voltage capacitors are discharged.
• Only the original measuring leads may be used. Their voltage, category and ampere rated powers must match those of the measuring device.
• If you have to take hold of the measuring spikes, do so by the grip sections only. Do not touch the measuring contacts whilst the measurement is being taken.

• Do not use the device in environments in which there are con-ductive particles or where the occurrence of moisture (in the form of condensation, for example) can create transient conductivity.

• If the device comes into contact with moisture or other conductive residue, work must not be carried out under voltage. At and above voltages of 25 V AC/60 V DC, the presence of moisture creates the risk of life-threatening electric shocks. Clean and dry the device before use. When using the device outdoors, make sure that the weather conditions are appropriate and/or that suitable protection measures are taken.

• If you are taking measurements in the hazardous vicinity of electrical installations, do not work alone and seek guidance from an electrically skilled person before starting work.
• Isolate the device from all current sources before opening the battery compartment cover.
• If possible, do not work alone.

Hold function

To briefly hold the current measured value, press the „HOLD" button. In order to take measurements, this function must be deactivated by pressing the button again.

12 Voltage detection, non-contact (AC warning)

The non-contact voltage detector integrated in the meter is able to detect AC voltages from 100 V to 600 V. Switch the device on and run the voltage sensor along the object to be tested (5 - 10 mm). The display (9) lights up if AC voltage is detected.

!

Non-contact voltage detection is no substitute for conventional voltage testing. As the device detects an electrical fi eld, it will react even to static charge.

Voltage detection, single-pole phase test

Remove the black test prod from the device. Turn the rotary switch to position „V AC/DC“ and connect the red test prod to the phase or neutral conductor. The red display (9) only lights up if the phase conductor is live. When the single-pole phase test is carried out on the outer conductor, the indicator function may be adversely affected under certain conditions (e.g. when insulating personnel protective equipment is used or at insulated locations).

!

The single-pole phase test is not suitable for checking for zero voltage. To do this, you need to carry out a two-pole phase test.

13 Flashlight function

To switch on the fl ashlight, press and hold down the corresponding button. The light switches itself off automatically as soon as the button is released.

14 Backlight

To switch the backlighting on, press the „Hold“ button (11) and hold it down for 2 seconds. Press the „Hold“ button twice, to switch the backlighting off.

15 Calibration

The meter needs to be calibrated and tested on a regular basis to ensure it produces accurate measurement results. We recommend carrying out calibration once a year.
