PIN-112

Continuity test

Warning! To avoid electric shocks never measure

connections with live circuits or wires.

1. Switch the function switch to the

position.

2. Insert the banana plug of the black testing wire in

the negative (3)COM connection and the banana

plug of the red testing wire in the positive (5)

connection.

3. Touch the circuit or wire you want to check with

the test probe tips.

4. If the resistance is lower than approx. 100 Ω an

acoustic signal is sounded. The display will also

show the actual resistance.

Diode test

Warning! To avoid electric shocks do not test live

diodes.

1. Insert the banana plug of the black testing wire in

the negative (3) COM input and the banana plug of

the red test wire in the positive (5) connection.

2. Switch the switch to

3. Place the measuring heads on the diode to be

tested (red on (+) anode, black on (-) cathode). The

forward voltage is 400 to 700mV. The reverse

voltage is shown by “1”. Short-circuited equipment

displays a result of nearly 0 mV. An open device is

shown by “1” for both poles.

Measurements DC amperage

Caution! Do not conduct current measurements in

the 10A range that last longer than 30 seconds. If

they last longer than 30 seconds this can cause

damage to the meter and/or testing wires.

1. Insert the banana plug of the black test wire in the

negative (3) COM input

2. For current measurements to 200 mA DC switch

the function switch to the 200mA position and insert

the banana plug of the red test wire in the positive

(5) connection. If the value is too low you can lower

the position to 20mA or 2000μA.

3. For current measurements from 10 A switch the

function switch to 10A and insert the bananaplug of

the red testing wire in the 10A input (4).

4. Switch off the current in the circuit to be

measured. Break the circuit where you want to

measure the current.

5. Place the black measuring head on the negative

side of the circuit. Place the red measuring head on

the positive side of the circuit.

6. Put power on the circuit

7. Read the current on the display. For mA

measurements select a lower mA position with the

function switch to obtain a result with a higher

resolution. The display mentions the decimal point

and the value.

Transistor hFE measurements

1. Switch the range switch to the hFE position

2. Determine if the transistor is an NPN or PNP type

and place the emitter, basis and collector in the

openings in the hFE plug on the front panel.

3. The meter shows the approximative hFE value for

base current 10uA and VCA 2.8V

Replacing the battery

Warning! To prevent electric shocks you must

disconnect the testing wires from any power sources

before you open the cover of the battery

compartment.

1. When the batteries are nearly empty the

message "BAT" appears on the right of the display.

The battery must then be replaced.

2. Follow the instructions for replacing batteries.

See the paragraph on changing the battery in this

manual.

3. Dispose of old batteries at a collection point.

Warning! To prevent electric shocks you may not

use the meter until the cover of the battery

compartment has been replaced and fastened.

Replacing batteries

1. Disconnect the meter's testing wires.

2. Remove the rubber protection

3. Open the battery cover by removing the screw

with a screwdriver.

4. Place the battery in the compartment. Ensure the

correct polarity.

5. Replace the battery cover. Fasten the cover with

the screw.

Opm.: If your meter is not functioning properly you

must check the fusing and the battery to make sure

they are still in working order and correctly fitted.

Replacing the fusing

Warning! To prevent electric shocks you must

disconnect the testing wires from any power sources

before you open the cover of the fuse compartment.

1. Disconnect the testing wires from the meter and

all items to be tested.

2. Remove the rubber protection

3. Open the fusing compartment cover by removing

the screw in the cover.

4. Remove the old fusing from the compartment by

carefully pulling it out.

5. Place the new fusing in the holder.

6. Always use fusing of the correct size and

specification (10A/250V fast-reacting for the 10A

range).

7. Replace the fusing cover. Insert the screw and

tighten firmly.
