(5) Frequency and Duty Cycle Measurement
1. Connect the black test lead to the “COM” socket and the red test lead to
the “VWHz” socket.
2. Set the selector switch to the “Hz” or “Duty” position.
3. Connect the probes across the source or load under measurement.
(6) hFE Test
1. Set the selector switch to the desired “hFE” position (PNP or NPN type
transistor).
2. Never apply an external voltage to the h
FE sockets. Damage to the meter
may result.
3.
Plug the transistor directly into the hFE socket. The socket is labeled E, B,
and C for Emitter, Base, and Collector.
4. Read the hFE (beta or DC current gain) in the display.
(7) Relative Value Display
Press the “REL” button on the meter to use the relative measurement
mode. The present value will be stored in memory. The new display value
is equal to the measurement value minus the stored value.
Example:
When you test the capacitance, you can use the Relative function to
eliminate the zero error.
(8) Auto Power Off and Disable
1. When the meter has been turned on for 15 minutes without any action
from the users, the meter will automatically turn itself off.
2. To disable the Auto Power Off function, press any button when the meter
is on or switch the selector switch.
