OPERATION
•
Boot check
•
Power on the unit at the rear followed by the soft power
button on the front panel.
•
The oscilloscope then run through a set on self test
functions followed by the display screen showing.
•
Take the probe and connect its BNC header to the
BNC terminal of the oscilloscope. Connect the probe's
main alligator clip to the "Calibration terminal" and the
ground clip also connected to the "Ground terminal".
•
Press UTILITY button then F1 and the screen will display DEFAULT SETUP.
Note: The meter has dual input channels plus one external trigger input channel.
•
Press CH1 to enter channel 1 menu.
•
Connect the probe to the CH1 input.
•
Set the probe attenuation switch to 10X position.
Note: The oscilloscope attenuation has to be set as well.
•
Press F4 until 10X displays. This changes the vertical range multiple to ensure the
measurement result correctly reflects the amplitude of the measured signal.
•
Connect both probe and ground clamp to the corresponding signal terminals.
•
Press AUTO and a square wave of about 3V at 1kHz is displayed.
•
Press OFF then CH2 and repeat for channel 2.
Probe compensation
•
Perform this adjustment when connecting the probes to any input channel for the
first time or errors in the measurement may result.
•
Connect the probe tip to the probe compensator's signal output connector and
connect the ground clamp to the earth wire of the probe compensator.
•
Enable CH1 and press AUTO.
•
Observe the shape of the displayed waveform.
•
Adjust the variable capacitor on the probe with an insulated screwdriver until a
correct waveform is achieved.
AUTOSET WAVEFORM DISPLAY
•
The oscilloscope features an AUTOSET function which automatically adjusts the
vertical deflection factor, scanning time base and trigger mode based on the input
signal until the most appropriate waveform is displayed.
•
This function only operates when the signal to be measured is 50Hz or above and
the duty ratio is larger than 1%.
