Offset Range - Tektronix P6245 Manual De Instrucciones

Offset Range

Use this procedure to adjust the offset range of the probe. The offset
zero of the probe should be checked before making any adjustment
to the offset range.
The offset range of the probe is approximately - - 10 to +10 volts. The
offset range is not warranted; however, this adjustment procedure is
provided for your convenience.
NOTE. If you are using an 1103 Probe Power Supply, make sure that
the oscilloscope is set to 50Ω termination with DC coupling.
See Figure 4- - 4 for the location of the offset range adjustment.
1. Set the power supply (using the DMM) to +10.00 VDC. (If
10.00 V cannot be set exactly, set the power supply just below
10.00 V.)
2. Connect the probe to the power supply as shown in Figure 4- - 3.
3. Set the channel's vertical offset to match the DMM reading.
4. Set the channel's vertical range to 0.1V/div.
5. Observe the DC value of the displayed trace.
6. Adjust Offset Range for an oscilloscope reading that matches the
DMM reading.
NOTE. After the offset zero and offset range have been adjusted,
perform a probe calibration and functional check to verify perfor-
mance.
