GENERAL
SPECIFICATIONS
Hold
: Contact can be used to signal the HOLD situation.
Fail safe
: Contact S4 is programmed as a fail-safe contact
(*)Note: When contact output current is more than 4 Amps, ambient temperature should be less
than 40 ºC.
F) Contact input
: Remote range switching to 10 times the programmed range.
Contact open
: If impedance > 100 kΩ: Range 1
(“Programmed range for mA1 output" is "Range 1.”)
Contact closed
: If impedance < 10 Ω: 10 x Range 1
G) Temperature compensation
Function
: Automatic or manual, for temperature ranges mentioned under B
(inputs).
Reference temp. : programmable from 0 to 100 ºC or 30 - 210 ºF (default 25 ºC).
H) 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.
I) Calibration
: Semi-automatic calibration using pre-configured OIML (KCl) buffer
tables, with automatic stability check. Manual adjustment to grab sample
J) Logbook
: Software record of important events and diagnostic data readily available
in the display or through HART
®
.
K) 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.
