Resistance Tests (Option 20 Only); Ohm Test - Navair 17-20AQ-347 Technical Manual

4.3 RESISTANCE TESTS (OPTION 20 ONLY)

4.3.1 Connect the 10 Ω standard resistor (item 2.3) to the TI as shown in Figure 7.

STANDARD RESISTOR
4.3.2 To measure the 10 Ω standard resistor, perform these steps:
Depress the TI OHMS pushbutton
Depress the TI CONFIG pushbutton
Select the CHG function
Select the Tru Ω function
Select the 10 Ω range
Depress the TI CONFIG pushbutton
Select the Resl function
Select 5 digit resolution
Depress the TI OHMS pushbutton
4.3.3 Connect a short across the 10 Ω standard resistor.
4.3.4 Depress the TI ZERO pushbutton. Wait until the TI BUSY light is extinguished.
4.3.5 Remove the short from across the 10 Ω standard resistor.
4.3.6 Using Figure 7 for the test setup, connect each of the standard resistors required for the measurements tabulated in the
following table. Set the TI ohms range manually (using the correct pushbuttons) to the range indicated. For each measurement,
verify that the TI indication is within the tolerance limits listed.
