Balancing; Zero Balance; Zero Balance Or Adjustment (Without Electronics) - HBM WA Series Mounting Instructions

Balancing

5 Balancing
The transducer and plunger are arranged by Ident. No. to prevent transposi­
tion. Plungers and coil systems that have not been balanced with one another
can give rise to measurement errors in excess of 1%.
Large measurement errors can also occur, if the plunger is deformed or dam­
aged. In case of replacement, the complete transducer (plunger and trans­
ducer) needs to be sent to HBM. The new core is adapted at HBM.
CAUTION
The transducer and plunger must not be transposed.

Zero balance or adjustment (without electronics)

Plunger (WA/...-L)
The plunger has a threaded piece for connecting it to the measurement object.
S Insert the plunger into the transducer as far as the first marking ring (the
projecting part of the plunger corresponds to size C, see page 24
"Dimensions").
S for the WA2: push in the core until the 0 ±1mV/V display. This requires an
amplifier providing tare and zero functions for zero balance.
The amplifier output signal is then zero balanced.
