3-1-5 BENCH TEST n Bench test shall be performed by a qualified aircrew survival equipmentman (PR). n The Tests shall be performed as close to NTP as possible (+15 o and 760 mm Hg.) n Where specified, test results shall be recorded on the Performance Test Sheet Performance Test SheetPerformance Test SheetNOTE: Before the following bench tests are performed, a DC power supply shall be acquired that is capable of providing an output of 3.75 Vdc @ 1 amp. Prior to testing, the Digital Test set shall have successfully passed its functional test.
