·
Selectable PID controller on main analog output. PID controller can operate with
instrument configured as loop-power transmitter, or as one of the two outputs on
the AC powered instrument. PID includes manual operation feature, and
diagnostic “stuck-controller” timer for relay notification of control problems.
·
Selectable Output Fail Alarm feature on Relay B allows system diagnostic
failures to be sent to external monitoring systems.
·
Large, high contrast, custom LCD display with LED back light provides excellent
readability in any light conditions. The secondary line of display utilizes 5x7 dot
matrix characters for clear message display. Two of four measured parameters
may be on the display simultaneously.
·
Diagnostic messages provide a clear description of any problem with no
confusing error codes to look up. Messages are also included for diagnosing
calibration problems.
·
Quick and easy one-point calibration method, air calibration method, and sensor
zero-cal. To provide high accuracy, all calibration methods include stability
monitors that check temperature and D.O. stability before accepting data.
·
High accuracy three-wire Pt1000 temperature input. Temperature element can
be user calibrated.
·
Security lock feature to prevent unauthorized tampering with transmitter settings.
All settings can be viewed while locked, but they cannot be changed.
·
High reliability, microprocessor-based system with non-volatile memory back-up
that utilizes no batteries. Low mass, surface mount PCB construction containing
no adjustment potentiometers. All factory calibrations stored in non-volatile
EEPROM.
