Operation

AC/DC VOLTAGE MEASUREMENTS

CAUTION: Do not measure AC/ DC voltages if a motor on the circuit is being switched ON or OFF. Large voltage surges may occur that can damage the meter.

1. Insert the black test lead into the negative COM terminal and the red test lead into the positive V terminal.

2. Set the function switch to VAC or VDC position.

3. Connect the test leads in parallel to the circuit under test.

4. Read the voltage measurement on the LCD display.

AC/DC CURRENT MEASUREMENTS

1. Set the function switch to the µA/mA position.

2. Insert the black test lead into the negative COM terminal and the red test lead into the positive µA/mA terminal.

3. For current measurements up to 2000 µA DC/AC, set the function switch to the mA position

7

4. Press the MODE button to indicate “DC” / “AC” on the display.

5. Remove power from the circuit under test, then open up the circuit at the point where you wish to measure current.

6. Touch the black test probe tip to the negative side of the circuit.

Touch the red test probe tip to the positive side of the circuit.

7. Apply power to the circuit.

8. Read the current in the display

RESISTANCE MEASUREMENT

WARNING: To avoid electric shock, disconnect power to the unit under test and discharge all capacitors before taking any resistance measurements. Remove the batteries and unplug the line cords.

1. Set the function switch to the Ω position.

2. Insert the black test lead into the negative COM terminal and the red test lead into the positive Ω terminal.

3. Touch the test probe tips across the circuit or part under test. It is best to disconnect one side of the part under test so the rest of the circuit will not interfere with the resistance reading.

4. Read the resistance in the display

CONTINUITY CHECK

WARNING: To avoid electric shock, never measure continuity on circuits or wires that have voltage on them.

1. Set the function switch to the position.

REPLACING THE BATTERY

1. Remove the bottom cover and secure the screw.

2. Replace old battery with fresh Two 1.5V AAA & 9V type battery.

3. Replace the bottom cover and secure the screw.

REPLACING THE FUSES

WARNING: To avoid electric shock, disconnect the test leads from any source of voltage before removing the fuse cover.

1. Disconnect the test leads from the meter.

2. Remove the protective rubber holster.

3. Remove the battery cover (two “B” screws) and the battery.

4. Remove the four “A” screws securing the rear cover.

5. Lift the center circuit board straight up from the connectors to gain access to the fuse holders.

6. Gently remove the old fuse and install the new fuse into the holder.

7. Always use a fuse of the proper size and value

(0.2A/250V fast blow for the 200mA range).

8.

Align the center board with the connectors and gently

10

press into place.

9.

Replace and secure the rear cover, battery and battery cover.

Multi-Network Modular Cable Tester Operation

Note: Make sure the battery power is sufficient. Insufficient battery power will lead to dimmed LEDs and incorrect results.

10 Base-T Test

1. Plug one end of the tested cable into the transmitting RJ45 jack on the master unit marked with a ' 回 ' and the other end of the cable into the remaining receiving RJ45 jack.

2. Slide power switch on. The upper row of LEDs will start to scan in sequence if the Auto/Manual button is set on

"Auto" mode. The LED for pin 1 will light up if the button is in "Manual" mode.

3. Switch back and forth from Auto or Manual scanning mode by pressing the Auto/Manual button on the side of the master-testing unit.

4. Once both ends of the cable are plugged in properly, the second row of LEDs will illuminate according to the corresponding LEDs in the top row.

5. Read the results of the LED display for the pin configuration status of the tested cable. If you fail to read the results the first time in Auto mode, you may wait for the second LED scan, or simply switch to Manual mode for pin by pin testing. In Manual mode, pressing the square "Test" button will advance testing to the next pin.

RJ11 Modular Cable Test

Please follow directions for the UTP/STP Cable Test anduse the operations manual for the correct LED pin out display

Coaxial Cable Test

1.Plug the two attached BNC adapter cables on both RJ45 jacks. Then connect the tested cable to each end of the

BNC adapter cables

2. For the remaining testing procedures, please refer to

10Base-T Test steps 2 to 5.

Note:

1. The center pin of BNC should be read on LED 2.

2. As Coaxial cable has only two wires, we suggest you read the result of the LED scan using Manual mode.

Remote Test

1. Plug one end of the tested cable to the transmitting RJ45 jack on the master unit marked with a ' ' and plug the other end into the remote terminator. If the tested cable is installed in a patch panel or wall plate, you may use the included patch cable to solve the connector gender problem.

2. Now, set the Auto/Manual switch to Auto mode for one-persontesting.

3. Read the test results from the LED display on remote terminator.

Note: The LED display on the remote unit will scan in sequencecorresponding to the transmitting end of the master unit.
