AOIP Micro-Ohmmeters are applying in Earth bonding and Metallization tests

• Customer: AIRBUS aircraft part production suppliers
• Goal: riveting door test / verify earth bonding
• Equipment: OM16
• Application: earth bonding and metallization.

1. Measure under 10A with high resolution 0,1µohm.
2. Small diameter kelvin test probes.

• Software is used in order to proceed to test onsite , save values and download when back to the office.
• Reproducibility: All parts of an aircraft, from flight commands to the undercarriage must be tested in earth bonding and continuity.
• All aircraft sub manufacturers must follow the rules

• Customer: EUROCOPTER (EADS group)
• Goal: verify that no electrostatic charges is stored on a particular points. NO CHARGE = NO EXPLOSION
• Equipment: OM16
• Application: earth bonding and metallization. Metallization is performed between several points of the aircraft or helicopter.

1. Metal part: Test under 10A (not more than 10A)
2. Composite part : Test under 1A (< 1A)

• For convenience, the OM16 has been modified to offer a removable top: It was easier to use in small volume as a cockpit of an helicopter.

Aoip Micro-Ohmmeters are applying in Carbon brush control

• Customer: Motor manufacturer
• Goal: control of carbon brushes
• Equipment: 2 x OM16 + Kelvin test probes
• Application:

1. On a motor when current is crossing the brushes, a temperature rising can occur and the carbon brushes can melt, the resistance value must be very low. 
2. With OM16, a test can be performed on manufacturing process, threshold values are programmed and if one of them is crossed, the beeper indicates it to the operator.

• Test installed on a production site

AOIP Micro-Ohmmeters are applying in Welding lead control

• Customer: PSA, Renault
• Goal: cable test between power supply and the welding clamp of robot / preventive maintenance
• Equipment: OM16
• Application:

1. The resistance measurement allows to determine the state of wear of cable. In this way it is possible to replace only the cable damaged.

AOIP Micro-Ohmmeters are applying in Coil test

• Customer: ITT Automotive
• Goal: coil test of solenoid valve
• Equipment: OM16
• Application:

1. The value of coil resistance must be located between two values. Two thresholds are setup, on the production line when test is performed if the operator hears a beep, the product is  rejected.

AOIP Micro-Ohmmeters are applying in Quality test

• Customer: LEGRAND
• Goal: circuit breaker quality test
• Equipment: OM21
• Application:

1. Check whether the resistance of each pole of the circuit breaker is in the specified values.

• Test in end of production line

AOIP Micro-Ohmmeters are applying in Length cable test

• Customer: NEXANS
• Goal: verify the resistance of cable coil
• Equipment: OM21
• Application:

1. Determine the real length of cable

• Before the shipment
