Appendix B: 150 ohm Cables
Working with 150 Ohm Cables
If you are using 150 ohm cable, adjust the minimum and maximum Impedance limits ±10% to 135
and 165 ohms.
First, make sure that the cable type for which you are changing the Impedance limits has been
selected as the default cable type. To select the default cable type, press
Cable (F1) from the
Ready screen, highlight the desired cable type, and press Default (F1).
To display the IMPEDANCE LIMITS screen, press the Extended Functions key, then select
Setup Autotest , then highlight the Autotest to edit, then press Edit (F2), then select Limits , then
select Impedance .
Press the
Ñ
or
Ò
arrow keys to highlight the field to edit. If your Scanner has an alphanumeric
overlay on the keypad, use the keypad to enter the limits. If your Scanner does not have an
alphanumeric overlay, press
Edit (F2) to display the edit screen. Change the Minimum limit to 135
and the Maximum limit to 165. See Chapter 4: Editing, Printing & Updating for more
information on editing.
After editing, press Save (F1) to store the new limits and press the ESCAPE key to exit.
