1. Continuity test

Ref. 4.5.2 Kalamos manual: "Installation and Operating Instructions for Locate Type M-4".

1.1

• SW1 = TEST CONTINUITY
• SW2 = ODD
• B switch down, for each trace
• Result trace 1-50 : 0 ohm = OK

1.2

• SW1 = TEST CONTINUITY
• SW2 = EVEN
• B switch down, for each trace
• Result trace 1-50 : 0 ohm = OK

2. Leakage test

Ref. 4.6.3 Kalamos manual

Measured trace 1-50: OK.

3. Measuring while winch is rotating

Repeated test 1.1 and 1.2 while winch rotated. No intermittent errors observed.
