IP testers

IP-1 tester

Purpose

The IP-1 tester is designed to execute accept-to-overhaul check and operability test of helicopter equipment during maintenance and overhaul, and to execute adjustment and repair works.

The IP-1 tester conducts fault diagnosis and check of set of the 2ИА-6 exhaust gas temperature indicating system.

The IP-1 monitors and measures parameters of the equipment under test according to maintenance manual for the set of the 2ИА-6 exhaust gas temperature indicating system under test.

The IP-1 used power supply from network between 100 and 240 V, 50/60 Hz.

Replaceable equipment:

 The УПТ-1М test set

 The КП-5 tester

3. Fixed support.



IP-2 tester

Purpose

The IP-2 tester is designed to execute accept-to-overhaul check and operability test of helicopter equipment during maintenance and overhaul, and to execute adjustment and repair works.

The IP-2 tester is designed to test a set of the ИР-117 EPR indicator in the following composition:

 The ДВК altitude sensor;

 Two ПМ-10МР pressure probes;

 The УР-117 EPR indicator.

The IP-2 monitors and measures parameters of the equipment under test according to maintenance manual for the set of the ИР-117 EPR indicator under test ИП-2.

The IP-2 used power supply from grounded network between 100 and 240 V, 50/60 Hz.
