-20-5. Operation 5.1. Front Panel Description

battery is weak, a "LO BAT" or "BAT" sign will appear on the left of Display. If this does not appear on the display proceed as below. See "Maintenance" if the battery has to be replaced.

2. The warning sign next to the test leads jack is for warning that

the input voltage or current should not exceed the indicated values. This is to prevent damage to the internal circuitry.

3. The function switch should be set to the range which you want

to test before operation. 5.3. DC Voltage Measurement

1. Connect the black test lead to the COM jack and the red test

lead to the V/Ω/ mA- jack.

2. Set the function switch to the DC V range to be used and

connect the test leads across the source or load under measurement. Note:

1. If the voltage range is not known beforehand set the function

switch to the highest range and work down.

2. When only the figure "OL" is displayed, overrange is being

indicated and the Function switch must be set to a higher range.

3. CAUTION: Do not apply more than 600 V to the input.

Indication is possible at higher voltages but there is danger of damaging the internal circuitry.

4. Use extreme caution to avoid contact with high tension circuits

when measuring high voltage.

1. Connect the black test lead to the COM jack and the red test

lead to the V/Ω/ mA-jack.

2. Set function switch to the AC V range to be used and connect

the test leads across the source or load under measurement. Note:

1. If the voltage range is not known beforehand set the function

switch to the highest range and work down.

2. Caution: Do not apply more than 600 V

rms to the input. Indication is possible at higher voltages but there is danger of damaging the internal circuitry.

3. Use extreme caution to avoid contact with high tension circuits

when measuring high voltage. 5.5. DC Current Measurement

1. Connect the black test lead to the COM jack and the red test

lead to the V/Ω/ mA-jack for a max. of 200 mA. For a maximum of 10 A, move the red test lead to the 10 A jack. Set the function switch to the DC A range to be used and connect the test leads in series with the load under measurement. Note:

1. If the current range is not known beforehand, set the

FUNCTION switch to the highest range and work down.

2. When only the figure "OL" is displayed overrange is being

indicated and the FUNCTION switch must be set at higher range.

-23-3. Caution: The maximum input current is 200 mA, or 10 A depending upon the jack used. Excessive current will blow the fuse which must be replaced.

4. Replace the blown fuse only with a fuse with the same ratings

and dimensions. 5.6. Resistance Measurement

1. Connect the black test lead to the COM jack and the red test

lead to the V/Ω/-mA- jack. (Note: The polarity of the red test lead is "+")

2. Set the function switch to the Ω range to be used and connect

the test leads across the resistance under measurement. Note:

1. If the resistance value being measured exceeds the maximum

voltage of the range selected, an over-range indication will be displayed "OL". Select a higher range. For resistance approx. 1 MΩ and above, the meter may take a few seconds to stabilize. This is normal for high resistance readings.

2. When the input is not connected, i. e. at open circuit, the

figure "OL" will be displayed for the overrange condition.

3. When checking in-circuit resistance, be sure the circuit under

test has all power removed and that all capacitors are fully discharged. 5.7. Diode Measurement

1. Connect the black test lead to the COM jack and the red test

lead to the V/Ω/-mA-jack. (Note: the polarity of the red test lead is "+")

2. Set the function switch to the -range an connect the test

leads across the diode under measurement.

1. When the input is not connected, i. e. at open circuit, the

figure "OL" will be displayed for the overrange condition.

2. There is 1 mA current flow through the device under test

3. The meter displays the forward voltage drop in millivolts,

and overload when the diode is reversed. 5.8. Battery test function With this function you can test batteries with a load in form of a resistance, resulting in a more accurate assessment of the battery power as in the pure tension test. This measurement function is not suitable for testing of button cells, because they are not designed for high load. Load ranges 1,5 V/13,4 for AAA/UM4 & AA/UM3 batteries 9 V/1,4 k for 9V (NEDA 1604, 6F22, 006P) batteries WARNING! If not handled carefully, batteries and accumulators can cause by sparks or even an explosion of the battery through a short-circuit. Make sure that the battery poles are never shorted by metallic items.

1. Connect the black test lead into the “COM” socked and the red

test lead into the “V//mA” socket.

2. Turn the rotary switch to the battery test position 1,5 V or 9 V

range, which the nominal voltage of the test battery meets.

3. Connect both test probes to the battery to be measured.

-25-6. Maintenance Your digital multimeter is a precision electronic devise. Do not tamper with the circuitry. To avoid damage: a) Never connect more than 600 V DC or AC rms b) Never connect a source of voltage with function switch on Ω position and - position. c) Never operate the DMM unless the battery cover is in place and fully closed. d) Battery and/or fuse replacement should only be done after the test leads have been disconnected and power is off. 6.1. Battery Replacement Note the condition of the 9-V-battery using the procedure described above. If the battery needs to be replaced, open the back cover, remove the spent battery and replace with a battery of the same type. Batteries, which are used up dispose duly. Used up batteries are hazardous and must be given in the for this being supposed collective container. 6.2. Statutory Notification about the Battery Regulations The delivery of many devices includes batteries, which for example serve to operate the remote control. There also could be batteries or accumulators built into the device itself.
