The probe menu includes INP 1/INP 2, SELECT PROBE, EDIT PROBE, CAL
PROBE, and PROBE DISK soft-keys. If the 2590 Scanner is connected to the
1575/1590, the first soft-key will appear as SELECT CHAN instead. To change
the probe definition for a particular channel, first use INP 1/INP 2 to select the
channel to edit then use SELECT PROBE to assign a different probe number or
EDIT PROBE to change the parameters.

Select Channel

The INP 1/INP 2 soft-key allows you to select the channel for which you want
to edit the probe parameters. This function does not select a channel to mea-
sure. When you first enter the probe menu, the channel that is currently being
measured is selected. An asterisk (*) appears next to INP 1 or INP 2 to indicate
the selected channel. Press this soft-key to select the other channel for editing.
Note that this soft-key does not actually change the channel being measured.

Select Probe

The SELECT PROBE soft-key allows you to choose which probe definition to
use with the selected channel. When you press this soft-key a list of probe defi-
nitions appears with the serial numbers of the probes. Use the U and D but-
tons to move to the desired probe number and press Enter. The probe window
will be updated to show the parameters for the selected probe. One restriction is
you can not select a probe for INPUT 2 that has EXTERNAL selected as the
reference.

Edit Probe

The EDIT PROBE soft-key is used to set the parameters included in a probe
definition. You will be prompted to enter the probe number to edit. Enter two
digits for the probe number (enter 01 for probe number 1, 20 for probe number
20). Then press the Enter button twice. After a probe is selected a new window
will appear showing the probe parameters. Use the U and D buttons to move
up and down the list. The window will scroll if needed. You can edit any or all
of the parameters in any order. When you are finished, press Exit to return to
the menu.
NOTE: Be sure to press Enter after changing a parameter to store the
new value.
These parameters, described in the following sections, can be specified for the
probe:
• Serial number
• Conversion type (ITS-90, Callendar-Van Dusen, etc.)
• Reference resistor
• Current
