Note:
1. If the resistance value being measured exceeds the maximum value of

the range selected, an over-range indication will be displayed(“1”).
Select a higher range.

For resistance of approx. 1 Megohm and above, the meter may take a
few seconds to become stable. This is normal for high resistance readings.

2.. When the input is not connected, i.e. an open circuit, the figure’1’ will be

displayed for an over-range condition.

3. When testing in-circuit resistance, ensure all power has been removed

and all capacitors are fully discharged.

4. When using the 200Megohm range, the display is 10 counts. These counts

must be subtracted from the reading.... eg. when measuring a 100M

W

resistance, the reading will display 101.0.
The correct measuring result iis 101.0 - 1.0 = 100M

Diode Measurement

1. Connect the BLACK test lead to the COM jack and the RED test lead to the

V/

Ω 

jack.

 (Note: The polarity of the RED test lead is “+”).

2. Set the FUNCTION switch to the

position and connect the test

leads across the diode under test, red lead to the anode, black to the
cathode. Display shows the approx. forward voltage drop of the diode.

Continuity Test.

1. Connect the BLACK test lead to the COM jack and the RED test lead to the

V/

Ω 

jack.

 (Note: The polarity of the RED test lead is “+”).

2. Set the FUNCTION switch to the

position and Connect the test

leads to two points of circuit, if the resistance is lower  than approx. 70

,

the buzzer sounds.

Transistor hFE Test

1. Set the FUNCTION switch to the hFE range.

2. Determine whether the transistor is NPN or PNP and locate the Emitter,

Base and Collector  leads.  Insert the leads into the proper holes in the
socket on the front panel.

3. Display will read approx. hFE value at the test condition/Base Current

10µA VCE 3.2V
