Note:
• When the measured resistance is greater than 1MΩ,
wait a few seconds for readings to stabilize.This is
normal for high resistance measurements.
• When the circuit is open or leads not connected, the
display will show "1".
4.3 DC/AC Current
Warning
To avoid personal injury, damage to the meter or
device under test, always be sure to have the
rotary in the correct position and leads in the
correct jack before making current measurements.
• Turn the rotary switch to the proper current range.
• Connect the black test lead to the COM jack.If the
current to be measured is less than 200mA, connect the
red test lead to the mA jack; if the current to be measured
is greater than 200mA, connect the red test lead to the
10A jack.
• Break the circuit and connect the leads in series with the
circuit under test.
• Read the measured current on the display.When
measuring DC current, the display will show the polarity
of the red lead.
• If the display only shows "1", it indicates the input
exceeds the selected range.Move the rotary switch to a
higher range.
4.4 Diodes
Warning
Turn off all power and discharge all capacitors
completely before testing diodes.

• Turn the rotary switch to the
• Connect the red test lead to the
black test lead to the COM jack.
• Connect the red lead to the anode (+) and the black lead
to the cathode (-) of the diode.
• The meter displays the forward voltage drop of the
diode.If the leads are reversed, the display will show '1'.
4.5 hFE Transistor Gain
Warning
To prevent damage to the meter, make sure the
transistor is not connected to a circuit before
making measurements.
•
Turn the rotary switch to the hFE position.
• Connect the multi-function socket with the "+"end to
the hFE input jack and the "COM" end to the COM jack.
• Connect the transistor to the correct NPN or PNP slots
of the multi-function socket for measurement.
• Read the measured transistor gain on the display.
4.6 Continuity
Warning
Turn off all power and discharge all capacitors
completely before testing continuity.
•
Turn the rotary switch to the
• Connect the red test lead to the Ω input jack and the
black test lead to the COM jack.
• Connect the leads to the circuit under test.
• If the measured resistance is less than 50Ω, the buzzer
will sound.
