3.Making Measurements

Note: For the 4000 uF range, the measuring duration should be over 30 seconds.

(1) Rotate the rotary switch to

. Press three times to enter capacitance

measuring mode, the Farad units will be displayed.

Note: On B41T(+), rotate the rotary switch to

(2) Connect the black test lead to the

terminal and the red test lead to the

terminal.

(3) Probe the test points and read the display.

Measuring Frequency

Frequency ranges are 9.999 Hz, 99.99 Hz, 999.9 Hz, 9.999 kHz, 99.99 kHz, 999.9 kHz, and

9.999 MHz.

(1) Rotate the rotary switch to

(2) Connect the black test lead to the terminal and the red test lead to the

terminal.

(3) Probe the test points and read the display.

(4) Press

to switch between the frequency and duty cycle measurements.

When measuring AC voltage or AC current, press to cycle through frequency

measuring, duty cycle measuring, and original measuring.

Measuring Transistor — Not available on B41T(+)

Warning: To avoid electrical shock or damage to the instrument, do not apply

more than 250Vdc or 250Vac rms between the

terminal and

the

terminal.

(1) Rotate the rotary switch to .

(2) Connect the “+” plug of the multi-functional test socket to the

terminal

and the “COM” plug to the

terminal).

(3) Determine whether the transistor is NPN or PNP type and locate the Emitter, Base

and Collector leads. Insert leads of the transistor into the corresponding holes of the

multi-functional test socket.

(4) Read the hFE value.
