Units
2.Use the up and down arrow keys to select the units
you want to change. Press 
to change the units of measure. An “X” in a box indicates your choice.
Distance: Feet or Meters: This affects all distances displayed in the 965AMS
tester.
Degrees: Fahrenheit or Centigrade: This affects all
temperatures used in the 965AMS tester.
Filter: C-Message or CCITT: This affects the filter used in the POTS Noise function. Use the C-Message filter in the US and Canada. Use the CCITT (also called “Psophometric”) filter in all other countries.
The 965AMS tester features a dBrnPfilter for noise tests in New Zealand. To set the default noise filter to dBrnP, set Filter option to CCITT. This filter is used only in units sold in New Zealand; for all other countries, the CCITT option uses a dBrnOp filter. Noise test results will be displayed as dBrnP.
TDR: Vp (Velocity Propagation) or m/µS (meters per microsecond): This affects the TDR “velocity of
propagation.” Use “Vp” in the US and Canada. Use “m/µS” in other countries. Press OK to accept any changes and return. Use the

Voltage Termination
1. The Voltage Termination option allows you to select the input impedance of the 965AMS digital voltmeter (in supported countries only). The input impedance of the internal 965AMS voltmeter is normally 1Mohm. However, some legacy systems use voltage measurement systems
with input impedances of 100Kohms. This option is provided to maintain
measurement compatibility with those systems.
If 100Kohm termination is selected, the 965AMS tester will display ‘100K’ on the voltage measurement.
Use this menu to change the Voltage Termination. Use the up and down arrow keys to highlight Voltage Termination. Press Change to continue or press 
to quit without making changes.
