Allows to check the deviation of the connected cell in comparison with
an ideal cell.
Cell test
1.
Press
SET
.
2.
Press
¿
or
À
until the display shows [SEtuP] and press
CAL
to
continue or
SET
to cancel.
3.
Press
CAL
until the display shows [teSt EC]. Press
SET
if you want
to test your conductivity cell against the Ohm's law.
4.
The ideal conductivity is shown while a blinking [i] appears. Compare
the performance of the electrode with the theory (i.e.: cm
-1
= 1).

Press
CAL

SET
to cancel.
Relay
All relays can be programmed for controlling any of the high or low level
alarms or for connection in a general alarm situation (ALrM), e.g. when
an electrode breaks. The displayed possibilities depend from the
channel set-up (conductivity or °C).

2.
Press
¿
or
À
until the display shows [SEt reL] and press
CAL
to
continue or
SET
to cancel.
3.
The display shows e.g. [r1=EC1(H)], [r1=EC1(L)], [r1=EC2(H)],
[r1=EC2(L)], or [r1=ALrM]. Select the desired mode for relay-1 with
¿
or
À
and press
CAL
to continue with all the next relays (r2...r3) or
press
SET
to cancel.
RS232
It is recommended to decrease the BAUD rate in case of difficulties with
the digital connections, especially for long distances.

2.
Press
¿
or
À
until the display shows [SEtuP] and press
CAL
to
continue or
SET
to cancel.
3.
Press
CAL
until the display shows e.g. [br=2400]. Pre-set the desired
baud-rate (150...4800 b/s) with
¿
or
À
and press
CAL
.
4.
The display shows e.g. [rS=60] which means that data is transmitted
every 60 s during a normal measuring phase (no pre-set levels are
exceeded). Pre-set the desired time interval (0...9999 s) with
¿
or
À
.
Pre-set to zero if not required.
5.
The display shows e.g. [rS=15], while the (H) & (L) indicators are
blinking, which means that data is transmitted every 15 s when a pre-
set level is exceeded. Pre-set the desired time interval (0...9999 s)
with
¿
or
À
. Pre-set to zero if not required.
6.
Press
CAL
to continue or
SET
to cancel.
Oversampling
By using several subsequent measurements, readings become very
stable since it allows the digital filter to eliminate noise-peaks more
effectively.
