AC/DC current measurement

• Connect the red test lead to the µA/mA [6] input jack (max. 400mA) or

10A [7] input jack and the black test lead to the COM jack [5].

• Set the rotary switch [3] in the desired current range (<4mA: µA

<400mA: mA

, <10A: 10A ) and use the mode button [3] to

choose between AC and DC current.

• Open the circuit in which the current is to be measured and connect the

test leads to the circuit IN SERIES.

• Read the current value and the polarity of the red lead connection on the

LCD display.

Resistance, diode test and audible continuity test

• Connect the red test lead to the -jack [4] and the black test lead to the

COM jack [5] (the red lead has a positive polarity "+").

• Set the rotary switch [3] in the Ω range position. Do not apply input

voltage at this setting!

• Use the mode button [13] to choose between , diode or continuity test.

• If the resistance being measured is connected to a circuit, turn off the

power and discharge all capacitors before applying the test probes.

• Connect the test leads to the resistor to be measured and read the LCD

display.

Note:

wait a few seconds for a stable reading when measuring resistors >

• For diode tests, connect the red test lead to the anode of the diode to be

tested and the black test lead to the cathode of the diode. The approx.

forward voltage drop of the diode will be displayed (typically 0.400 –

0.700V). If the connection is reversed, the display will show “OL”.
