Fig. 6.1: Components Layout
 Terminal strip
CL 21, CL 22, CL 23: The three clamp strips CL 21, CL 22 and CL 23 com-
prise the individual screw clamps numbered 1 through 9. They serve for the
connection of the supply voltage, transducer and indicating or recording in-
strument resp., in accordance with the given contact allocations.
 Zero balance
P 21: The screw potentiometer P 21 serves to balance the zero output signal
of the connected transducer by up to "9 mV/V.
By reducing R 21 the zero balance range can the changed to "0.9 mV/V.
 Measuring range
S 21: The sliding switch is used to select either of the ranges "80 mV/V or
"8 mV/V.
Position 1 ¢MR 1 ¢80 mV/V
Position 2 ¢MR 2 ¢ 8 mV/V
Resistor R 39
124 k = 8 mV/V
12.4 k = 80 mV/V
