3. Press ENTER to exit the Battery Menu and save the settings.
Select popular settings and cable type
These setting are user preferences from the F2 through F5 menus. They include
backlight timing, contrast, vertical scale (Ohms), horizontal scale (range), big
numbers on/off, input channel, cable type, etc. When completed go to the next
steps to save all these settings.
Save INSTRUMENT SETUP
Steps
1. Press F4 and select MEMORY ACTION.
2. Select SAVE INST ONLY. This will open a screen to enter a save name.
3. Use the F keys and number keys to enter a name.
4. Press ENTER to save the setup and enter a number 1-9 for the memory slot.
5. Press ENTER to save the setup and exit.
Only one instrument setup is required to recover the Battery Menu correctly.
However, you can repeat this process to save up to 9 different setups, with
different cable types and other setting as desired. The saved settings can be
penciled into the matrix in the Operator Manual in Appendix C.
Soft Reset with RECALL INST
Steps
1. If your 20/20 TDR is not performing correctly (i.e. Measurement screen has
incomplete data, menu cursor will not move, etc.) perform the Soft Reset to restore
the program operation.
2. Turn the TDR off.
3. Turn the TDR on and immediately press the ENTER key 4-5 times rapidly.
4. The TDR will perform the housekeeping necessary to restore operation and stop
at a factory default Measurement Screen (normally 0-999 Ohms and Range about
5120 ft).
5. Press the F4 key and select MEMORY ACTION
6. Select RECALL INST and enter a memory slot 1 through 9 to recall.
7. Press ENTER to recall the instrument setup.
This action should avoid the issue of the battery menu changing the BATTERY TYPE
to NONE or ALKALINE after a Soft Reset. Both those battery types will turn the
TDR’s internal battery charger off. As a last check you might wish to select the
Battery Menu again to ensure the BATTERY TYPE is NICD NIMH. Also, the EST. RUN
TIME will display 0.0 HRS after a Soft Reset. After 1-3 re-charging cycles the
charger will learn the cell’s capacity and post valid EST. RUN TIME.
