15.2 Detection of Error sources (INF flag)

Measurement may be influenced by static or alternating magnetic fields and by metallic objects

near the sensor.

If no target ball is placed on the sensor, the “INF” flag

appears on display. That means that the probe is in

the infinity range.

Make sure that INF is shown so that correct

readings can be taken.

If the sensor is subject to some interference (e.g.

through electro-motors, transformers, potential

distribution or if a steel plate is near the sensor) the

INF flag disappears.

Try to move the sensor a little bit in order to locate the

source of interference. If you have detected the error

source, move the sensor away from it. As soon as the

“INF” flag appears on display, the sensor is out of the

error source range and the gauge is ready again to

take correct measurements.

To be sure, take double the distance form the error

source.

In the default measure mode using a target ball, it is

not of importance if the “INF”-flag disappears.
