Range Potentiometers.
Fig. 4.3. Range Potentiometer.
The following Range Potentiometers are available:
Type
Range Accuracy
ZR 0001 10-35 mY. Linear
2 % of fulI scale
ZR 0002 10-110 mY. Linear
2 % of fulI scale
ZR 0003*)
10
dB.
Logarithmic (100 mV -316 mY) ± 0.1 dB
ZR 0004
25 dB. Logarithmic
(10 mV -180 mY) ± 0.2 dB
ZR 0005**)
50
dB. Logarithmic ( 10 mV - 180 mY)
± 0.3 dB
ZR 0006
75 dB. Logarithmic (10 mV -56 V)
± 0.5 dB
*) To maintain the wide frequency range with an approximate accuracy it has been found
necessary to reduce
the maximum sensitivity for this Potentiometer to 100 mV.
U) Normally delivered with the Level Recorder.
