At this time the loop output automatically goes to 4 mA.
3. Hold the magnet over either the “Up” or “Down” magnetic switch
and adjust to the desired level.
4. Hold the magnet momentarily over the “S”- Enter switch.
The display will indicate “Set” momentarily then displays “Ihb”.
5. Hold the magnet momentarily over the “Z” Escape switch to place the
transmitter back into normal operation.
Calibration Frequency
All Series 5000 transmitters require calibration upon receipt from the factory (unless the
transmitter/sensor are part of the Cal-Plus program), after which, the calibration interval
for each transmitter should be independently established through a documented
procedure. Calibration frequencies will vary depending upon individual applications.
Harsh environments will generally require more frequent calibration.
At a minimum, it is recommended that these calibration frequencies be followed:
Zero Calibration: Upon system power-up; every 60 days or less; upon (new or old)
sensor re-connection to the transmitter. Oxygen Transmitter exception – every 90
days.
Span Calibration: Upon system power-up (unless sensor has been pre-calibrated);
every 90 days or less.
Oxygen Transmitter exception – every 30 days
Calibration Reminder...
• Document your calibration schedule requirements.
• Maintain an organized system to prevent confusion between
calibrated and un-calibrated sensors.
• Properly store all spare sensors
