Configuration
To set the probe offset, follow these steps:
1. Set the oscilloscope coupling to GND.
2. Use the vertical position control to set a zero reference level on
the oscilloscope display.
3. Set the oscilloscope coupling to DC and 5 V/div.
4. Attach the probe to the circuit.
5. Adjust the probe offset to bring the trace to the oscilloscope zero
reference.
6. Change the volts/division setting to the desired range, adjusting
the offset to keep the trace on the zero reference level.
NOTE. The P6245 has a ±10 V offset range. The linear operating
range is ±8 V. See Figure 1- - 1. Also, see page 2- - 1 for more
information.
If cursors are used on a TEKPROBE oscilloscope, the zero reference
will be at the probe offset voltage.
