These instructions must be followed in all respects. Repair and replacement of parts When opening the tester, live parts may be exposed. The tester must be disconnected from all voltage sources prior to repair or replacement of parts. If a repair cannot be avoided unless the tester is open and live, this must be performed by a qualified person who understands the danger involved. Faults and extraordinary stress When it must be assumed that safe operation is no longer possible, take the meter out of service and secure it against accidental use. It is assumed that safe operation is no longer possible, when the tester shows obvious signs of damage, when the tester no longer functions correctly, after prolonged storage under adverse conditions. ! Attention! The fixed test leads have a double insulation in different colors. You can readily recognize damaged leads by the light insulation on the inside. Meaning of the symbols on the device ! Warning of a danger point (Attention, refer to documentation) Double or reinforced all-insulation Mark approval by testing board EU-Conformity Mark This device may not be disposed of with the trash. Further information regarding the WEEE mark can be accessed on the Internet at www.gossenmetrawatt. com under the search term WEEE. GOSSEN METRAWATT GMBH Applications Applications / EN 61557 / VDE 0413 Measuring and monitoring facilities for testing the electrical safety in lines with nominal voltages up to AC 1000 V and DC 1500 V. Part 1 General; Part 2 Insulation resistance; Part 4 Resistance measuring devices. It is suited to measure the insulation resistance of electrically dead devices and systems having nominal voltages up to 500 V and to test the resistance of ground conductors, protective conductors and equipotential conductors including their connections and connectors. In addition, the tester has a 500 V measuring range for DC and AC voltage which complies with DIN VDE 0100 Part 610. This makes it particularly advantageous to test devices for the absence of voltage and to discharge capacitive devices under test. The most important applications of the insulation tester are found in testing of systems and appliances such as required by DIN VDE 0100, 0105, 0141, 0701 and 0702 specifications, for example. 3 Getting started 3.1 Inserting the batteries ! Attention! Make sure that the rotary switch (6) is set to the OFF position prior to opening the battery compartment and that the tester is completely disconnected from all external circuits! 1 Undo the two slotted screws on the bottom ot the tester with an adequate tool and remove the cover of the battery compartment. 1 Insert 6 each 1.5V mono-cells to IEC R20 (zinc-carbon) or to IEC LR20 (alkaline-maganese) in the battery compartment. paying attention to the correct polarity in line with the given symbols. 1 Replace the cover of the battery compartment and tighten the screws. 3.2 Testing the batteries 1 Set the rotary switch (6) to position -II-. The charging state of the six mono-cells is tested at this position. To simulate operating conditions, the lamp in the probe is switched on. The digital display shows the battery voltage at this load on the LCD display (5). GOSSEN METRAWATT GMBH At the same time, the analog indicator shows the nominal range of use of the battery voltage. You can quickly judge the charging state of the battery set by the location of the pointer. At the same time, the analog indicator shows the nominal range of use of the battery voltage. You can quickly judge the charging state of the battery set by the location of the pointer. The battery test is automatically stopped after about 10 seconds. The lamp goes out and HOLD is shown on the LCD dieplay (5) in addition to the digital display and the analog indication. This presentation is maintained until the tester automatically switches back to standby after approximately 3 minutes. until you press the measurement pushbutton (8) or until you set the rotary switch (6) to another position. You start a new battery test by pressing the measurement pushbutton (8). 3.3 Fastening the carrying strap and the probe holders Probe holder Carrying strap Catch Metriso 500D Fasten the carrying strap (14) and the two probe holders (12) and (13) as shown in the following figure. Make sure to fix the holder for the slim probe (10) at the left and the holder for the probe with lamp and pushbutton (9) at the right. GOSSEN METRAWATT GMBH 3.4 3.4 1 Set the rotary switch (6) from the OFF position to position 500 V , ISO-. or .. When set to the 500 V position, the measuring range for DC and AC voltage is switched on. Digital display and analog indication are presented. When set to the lSO-. position, the tester is switched to standby. The digital display only shows the decimal point together with the numeral 3 and the unit M., and the analog indicator shows the measuring range 500 V. When set to the . position, the tester is switched to standby. The digital display only shows the decimal point together with the number 30 and the unit .. After measuring at the . and ISO-. positions, the tester automatically switches to standby, when the rotary switch is not operated for approximately 3 minutes and when no other pushbutton is pressed when the measured value does not change for approximately 3 minutes when no voltage above 25 V is applied to the probes for more than 3 minutes on the 500 V range. 1 To reactivate the tester, press any pushbutton on the tester or the pushbutton (8) in the probe, or set the switch (6) to another position. CONTINUOUSLY ON When set to the ISO-. and . positions, the tester measures only as long as you keep the pushbutton (8) in the probe pressed (an exception is the AUTO function at position ., see section 8.1). When set to these positions, you also can switch the tester CONTINUOUSLY ON: 1 Briefly press the measurement pushbutton (1) on the tester. You can cancel CO...
