The JUMO dTRANS Az 01 (3) indicator/controller requires a standard
0(4) — 20 mA input signal that is proportional to the conductivity.
The conductivity transmitter JUMO CTI-Junior, type 202754 (2) provides such
a standard signal. The temperature probe that is integrated into the JUMO
CTI-Junior performs the temperature compensation for the conductivity
measurement and can also be used to control the temperature of the
substance being measured.

24 V DC
A combination of:
- (3) JUMO dTRANS Az 01,
(configured as a conductivity indicator, rAnG 22 to 25)
rAnG 22 -> no decimal places
rAnG 23 -> one decimal place
rAnG 24 -> two decimal places
rAnG 25 -> three decimal places
- (2) JUMO CTI-Junior, type 202754/xx-xxx/263 (conductivity transmitter)
- (1) Power supply for the JUMO CTI-Junior
(e.g. JUMO type PS5R-A-24)
The configuration level is unlocked,
"Unlocking the levels", page 27 (code word 0300)
The instrument is in the measurement mode,
"Operating modes and states", page 24.
Press the key twice, for more than 2 seconds, to access the
PGM
configuration level.
The lower display shows "C111".
