<2. GENERAL SPECIFICATIONS>
Control function;
On/Off
Adjustable damping
Expire time
Hold;
Contact can be used to signal the Hold situation.
Fail safe;
Contact S4 is programmed as failsafe contact.
*1:
When contact output current is more than 4 Amps, ambient temperature should be less than
40 ºC.
Contact input:
Remote range switching to 10 times the programmed range.
Contact open;
If impedance > 100 kΩ: 1 x Range
(When programmed range for mA output is conductivity).
Contact closed;
If impedance < 10 Ω: 10 x Range
Temperature compensation:
Function;
Automatic or manual, for temperature ranges mentioned under B
(inputs).
Reference temp.; programmable from 0 to 100ºC or 30 to 210 °F (default 25ºC).
Compensation algorithm
:
According IEC 60746-3 NaCl tables (default). Two independent user
programmable temperature coefficients, from 0% to 3.5% per ºC (ºF) by
adjustment or calibration.
Matrix compensation:
With conductivity function of concentration and
temperature. Choice out of 13 preprogrammed
matrixes and 2 100-points user-programmable
matrixes.
Calibration
:
Semi-automatic calibration using pre-configured OIML (KCl) stanard tables,
with automatic stability check. Manual adjustment to grab sample.
Logbook:
Software record of important events and diagnostic data readily available in
the display or through HART
®
.
Display:
Graphical Quarter VGA (320 x 240 pixels) LCD with LED backlight and
touchscreen. Plain language messages in English, German, French,
Spanish, Italian, Swedish, Portuguese and Japanese.
