3.1.4 Power supply 3.1.4.1 Batteries and storage batteries Both models, MiniTest 7400 FH and MiniTest 7200 FH, are powered by a set of four alkaline- manganese cells, 1.5V, AA LR6 size (Batteries included in the standard supply schedule.). As an alternative, both models may be operated on rechargeable NiMH (type AA-HR6) storage batteries or via a power supply unit (available as an option). -

Page 12: Sensor Stand
Both sensor types come with a spring-loaded V-grooved sensor stand. The use of the sensor stand ensures increased reproducibility of readings by adding stability of the sensor during measurement so that even small parts can be measured without problems. © ElektroPhysik MiniTest 7200 FH / MiniTest 7400 FH... -

Page 22: Correct Sensor Position
The reading will therefore be higher than the actual thickness. Remedy: Make sure to keep the sensor in perpendicular position to the sample. If necessary, use the sensor stand. © ElektroPhysik MiniTest 7200 FH / MiniTest 7400 FH... -
Page 23: Incorrect Readings Through Blocked Target Ball
Ferruginous particles in the material to be measured may lead to erratic readings because the ferruginous particles may influence the measuring signal. This will lead to readings smaller than the actual thickness. © ElektroPhysik MiniTest 7200 FH / MiniTest 7400 FH... -
Page 24: Calibration
In some cases it may become necessary to recalibrate if a new target ball is used (also if it has the same diameter as the previously used one). To be sure, check calibration in © ElektroPhysik MiniTest 7200 FH / MiniTest 7400 FH... -
