Procedure
The JUMO dTRANS Az 01 (1) indicator/controller requires a standard
0(4) — 20 mA input signal that is proportional to the conductivity.
The JUMO transmitter for free chlorine, type 202630 (2) provides such a
standard signal. A optional temperature probe (3) makes it possible to display
or control the temperature of the substance being measured.
As an option, the JUMO dTRANS Az can provide the supply voltage for the
JUMO transmitter for free chlorine, type 202630.
(2)
Example: a combination of
- (1) JUMO dTRANS Az 01,
(configured as a universal indicator, rAnG 27 to 30)
rAnG 27 -> no decimal places
rAnG 28 -> one decimal place
rAnG 29 -> two decimal places
rAnG 30 -> three decimal places
- (2) JUMO measuring cell for free chlorine, type 202630
- (3) optional temperature probe (Pt100 or Pt1000)
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.
