3. Danger of electric shock and other dangers

To avoid an electric shock, observe the precautions when working with voltages exceeding 120 V (60 V) DC or 50 V (25 V) eff AC. In accordance with DIN VDE these values represent the threshold contact voltages (values in brackets refer to limited ranges, e.g. in agricultural areas). The tester must not be used with the battery compartment open Before using the tester, ensure that the test lead and device are in perfect working order. Look out e.g. for broken cables or leaking batteries. Hold the tester and accessories by the designated grip areas only, the display elements must not be covered. Never touch the test probes. The tester may be used only within the specified measurement ranges and in low-voltage installations up to 690 V. The tester may be used only in the measuring circuit category it has been designed for. Before and after use, always check that the tester is in perfect working order (e.g. on a known voltage source). The tester must no longer be used if one or more functions fail or if no functionality is indicated.MD 1060, MD 1160

It is not permitted to use the tester during rain or precipitation. A perfect display is guaranteed only within a temperature range of -15°C to +55°C at an relative air humidity less than 85%. If the safety of the user cannot be guaranteed, the tester must be switched off and secured against unintentional use. Safety is no longer guaranteed e.g. in the following cases: − obvious damage − broken housing, cracks in housing − if the tester can no longer perform the required measurements/ tests − stored for too long in unfavorable conditions − damaged during transport − leaking batteries The tester complies with all EMC regulations. Nevertheless it can happen in rare cases that electric devices are disturbed by the electrical field of the tester or the tester is disturbed by electrical devices. Never use the tester in explosive environment Tester must be operated by trained users only Operational safety is no longer guaranteed if the tester is modified or altered. The tester may be opened by an authorized service technician only.

The tester may be used only under the conditions and for the purposes for which it was designed. Therefore, observe in particular the safety instructions, the technical data including environmental conditions.MD 1060, MD 1160

2. Plug on cover (GS38)

1. Buzzer hole for acoustic indication

5. LCD Display indication voltage, polarity and low battery (MD 1160)

6. Preparation for tests

6.1 Auto-power-on/ switching on

• The tester switches on when it detects continuity, an AC or DC voltage above approx. 10V or a live phase on L2 (single pole test).

• It can be switched on with the torch light button.

• Tester is automatically powered off after 5 sec when there is no signal contacted to the probes.

• The torch light switches off after approx. 10 sec.

• Connect both probes to the object under test.

• The voltage is indicated by LEDs and LCD (MD 1160 only)

• Buzzer sounds when a threshold voltage of approx. 38VAC or approx. 100 VDC is exceeded.

• Voltage polarity is indicated in following manner. AC: + and – 12V LED are on +DC: +12V LED is on -DC: -12V LED is on When the L2 probe + is the positive (negative) potential, the Polarity indication LED indicates “+DC” (“-DC”). During voltage test, L or R LED may light up. In case of empty batteries, the ELV LED lights up >50VAC, >120VDC

7.2 Single-pole phase test

Function of this test may not be fully achieved if the insulation condition/ grounding conditions of user or of the equipment under test aren’t good enough. Verification of live- circuit shouldn’t be dependent on this Single-pole phase test only, but on the voltage test.

• Hold the tester good in your hand. Connect the “L2 +” probe to the object under test. Live circuit LED lights up and buzzer sounds when a voltage of approx. 100V AC or more exists in the object under test. (Pol≥100VAC).

7.3 Phase rotation test

• L LED and R LED for Phase rotation test may operate on various wiring systems, but effective testing result can be obtained only on three-phase 4-wire system.

• Hold the tester good in your hand and connect both probes to the object under test.

• Phase-to-phase voltage is indicated by Voltage LEDs.

• R LED lights up for Right rotary field.

• L LED lights up for Left rotary field.

• Measurement principle: The instrument detects the phase rising order regarding the user as earth. Function of this test may not be fully achieved if the insulation condition/ grounding conditions of user or of the equipment under test is not good enough.MD 1060, MD 1160

Make sure the object under test isn’t live.

• Connect both test probes to the object under test. Continuity LED lights up and buzzer sounds continuously to indicate continuity

• Pressing the torch light button to turn on the light and after approx. 10s it will turn itself off

8. Battery Replacement

Remove the probes from any testing point, when opening the Battery case. Batteries are dead when the continuity test with both test probes connected cannot be done anymore. A battery symbol in the LCD indicates low battery. Follow the procedure below and replace batteries with new ones (type IEC LR03 1.5V).

• Unscrew the battery door, e.g. with a coin.

• Pull out the Battery door and replace the batteries. Insert new batteries according to the engraving on the Battery door.

• Re-assemble battery door. Confirm that the Battery door case is properly locked prior to measurements.MD 1060, MD 1160

Use a lightly damp cloth with neutral detergent for cleaning the instrument. Do not use abrasives or solvents. Do not expose the instrument to direct sun light, high temperature and humidity or dewfall. Remove batteries when the instrument will not be in use for a long period.MD 1060, MD 1160
