CALIBRATION – CONTINUED

7. Set battery disconnect switch and ignition switch to ON position (PLS: TM 9-2320-364-14&P, HEMTT: TM 9-

2320-326-14&P).

NOTE

Value should be approximately 15 mA when stowage guide is vertical and approximately 4

mA when guide is tilted fully toward rear.

8. Move stowage guide (Figure 5, Item 1) and watch values on multimeter. Values should range between 4 mA

and 15 mA (approximately) as stowage guide is moved.

9. If values are out of range, adjust placement of sensor arm (Figure 5, Item 2) on sensor linkage (Figure 5,

Item 4) by installing mounting hardware in different mounting locations (Figure 5, Item 3). Measure current at

new location to ensure value is between 4 mA and 15 mA.
