Fig. 5.1 Plunger with markings (zero balance)
Probe (WA/...-T)
The mechanical zero position of the displacement probe (size E, see chapter 9
"Dimensions", page 24) is derived for neutral position with probe tip extended.
Movement of the probe tip in the measurement direction by an initial stroke of
up to 0.5 mm has no effect on the technical data of the displacement probe.
Having chosen the position, any output signal still present should be reset to
zero on the amplifier. Initial stroke for the WA2 probe until 0±1mV/V is reached
on the amplifier.

Zero balance or adjustment (with electronics)

Loose plunger and probe version (WA/...-L/...-T)
The plunger has got a threaded connection piece for connection to the test
specimen. The mechanical zero position of the displacement probe (see
dimensions page 24) is derived for neutral position with probe tip extended. By
moving the loose plunger or probe tip in the direction of measurement until an
output signal of 0.5V +/- 0.05 V is displayed, the lower range value is reached.
At this position, the output signal at the subsequent electronics is to be
assigned to a displacement of 0.
CAUTION
The transducer and plunger must not be transposed. The same applies for the
amplifier and the transducer, if the amplifier can be separated from the trans­
ducer through a plug.
