Models for potentiometers and resistances
Panel meters to measure the position of a potentiometer with
nominal value between 200 Ohm and 20 KOhm. Measured
range from 0% to 100% of the potentiometer, with display
scalable in engineering units. Model to measure resistances
in 2 and 4 wire techniques, from 200 Ohms up to 200 KOhms,
with direct display of the resistance value in Ohms or KOhms.
Additional options with relay outputs (1 or 2 relay), analogue
outputs (in mA and Vdc), digital outputs in serial code (RS232
or RS485), parallel BCD code, display «Hold» function and
power options in AC and DC.

for Potentiometers
up to 20 KOhms
for Resistances
up to 200 KOhms
Instrument to measure the position of a potentiometer with
a range of 0% to 100% of the potentiometer. For all potentiometers with nominal values between 200 Ohm and 20
KOhm. Display scalable in engineering units (Kilos, mm, ...).
Connection with 3 wires.
Instrument to measure resistance signals up to 200 KOhms.
Different signal ranges selectable by internal jumpers. Measures with 2 and 4 wires technique for compensation of the
errors introduced by the ohm resistance of the wires. Direct
display of the value in Ohms.
READING SCALE SELECTION
READING SCALE SELECTION
Scale the reading to the desired value at full scale, by selecting the jumpers on the «MM» module, as shown on table
below, and select jumpers «D» to light the decimal point
(see figure 1 on page 4). Potentiometer «P2» allows manual
adjustment of reading at full-scale. Potentiometers «SPAN»
and «OFFSET» at the front of the instrument are for small
«on-the-field» error corrections on the scaled display.
Scale the desired measuring range, by selecting the jumpers
on the «MM» module, as shown on table below, and select
jumpers «D» to light the decimal point (see figure1 on page
4). Potentiometer «P2» allows manual adjustment of the
