4.2.4 Choosing electrolyte and measuring cell
Choose an appropriate electrolyte solution and
measuring cell according to the selection table. For
standard applications, the measuring cell type I should
be used. If however, your electrolyte solution shows an
index
5
(e.g. E6
5
for Zinc on Brass), the inner measuring
cell type II is to be used.
4.2.5 Filling in the electrolyte solution
Dip the inner measuring cell into the electrolyte bottle
and press the Pump-UP-key (18). Keep pressed down
until the electrolyte reaches the limits of the Max/Min
marking (44a). Place the inner measruing cell into the
outer one and seal it by means of the clamping fork (41).
Now measurement can start.
4.3 Taking readings
Press START-key. The launch of measuring procedure
is indicated by analogue meter (1) deflection. After that,
the needle returns to zero position. Deviations up to +/-
0.5 during measurement can be ignored.
The reading display (2) continuously shows the coating
thickness being removed.
During measuring, it can be switched from thickness to
cell voltage by pressing THICKNESS/VOLTAGE-key (8)
with the corresponding unit (microns/mils or Volts, re-
spectively) being shown on the alpha-numerical display
(3).
Shortly before the measurement being finished, a slow
analogue meter (1) deflection to the right can be ob-
served indicating the start of the voltage jump. A few
seconds later, the instruments cuts off the measuring
current and emits and audible signal. At the same time,
the continuous reading display (2) stops and displays
the de-plated coating thickness in microns or mils.
If you have switched to VOLTAGE display (measuring
cell voltage), the instruments switches automatically to
coating thickness at the end of measurement.
The readings are automatically stored in the statistics
memory and, if the printer is connected, printed-out along
with their current identification number.
If the reading is not be stored in the statistics, press
CLEAR-key (10) for deletion. Deletion is confirmed by
the printed message *CANCEL*.
