FREQUENCY (DUTY CYCLE) MEASUREMENTS (ELECTRONIC)

1. Set the rotary function switch to the green Hz/% position.

2. Insert the black lead banana plug into the

negative COM jack and the red test lead

banana

plug into the positive Hz jack.

3. Touch the test probe tips to the circuit under

test.

4. Read the frequency on the display.

5. Press the MODE button to indicate "%".

6. Read the % duty cycle in the display.

% 4 – 20mA MEASUREMENTS

1. Set up and connect as described for DC mA measurements.

2. Set the rotary function switch to the 4-20mA% position.

3. The meter will display loop current as a % with 0mA=-25%,

4mA=0%, 20mA=100%, and 24mA=125%.

a) Set the rotary function switch to the INSULATION position ,

and Press the RANGE button to chose one of the voltage which

display on the top left corner.

b)Connect two testing lines to the tested；

c)Push down and hold the "TEST" button /or press the " LOCK"

keystoke first and then the "TEST" button, if the tested is

electriferous and its voltage ( AC/DC) is over 30V, it will refuse work

and no high-voltage testing occurs, simultaneity, it shows ">30V" on

the LCD, the symbol "

" flashes, and the buzzer warns frequently.

if the tested is diselectriferous or its voltage is lower than 30V, it will

enter into the formal testing process and brings the high-voltage. on

the primary display, the insulation resistance in MΩ is indicated in-
