Part 2 – Mechanical Installation Transmitter Mounting Threaded inserts in the rear of the enclosure permit the attachment of brackets for securing the transmitter to a wall or pipe. An optional bracket is also available for “flush mounting” the transmitter into a panel, so that only the front cover protrudes.
Part 2 – Mechanical Installation Model F12/D Gas Transmitter Figure 3 Deep Enclosure dimensions Wall and Pipe Mounting A PVC mounting bracket with attachment screws is supplied with the transmitter. The transmitter is attached to the bracket using four flat head screws, and the bracket is attached to a wall or pipe by way of the four slots in each corner.
Part 2 – Mechanical Installation Model F12/D Gas Transmitter Panel Mounting (Remote Sensors Only) Figure 7 depicts the details for panel mounting the deep case. For this, a bracket attaches to the rear housing, and when adjusted, pulls the transmitter’s flange down against the adhesive side of the gasket supplied with the bracket (make certain to remove the protective paper first).

Part 4 – Operation Model F12/D Gas Transmitter Sensor Calibration Calibration Frequency While the transmitter itself requires no periodic calibration, H10 sensors should be “zero” and “span” calibrated every 3-6 months, based upon environmental factors. Sensors frequently exposed to dirt, oil mist, vapors, or very dry air, may require more frequent calibration.

Part 4 – Operation Model F12/D Gas Transmitter Sensor Span Calibration Span calibration* requires a bottled “span-gas” with a 500 cc/min regulator, calibration adapter, and a convenient length of ¼” tubing. The gas type and concentration used depends on the type of sensor installed.
Part 4 – Operation Model F12/D Gas Transmitter Sensor Calibration History A calibration record is written into the sensor memory each time a zero or span calibration is performed. Enough memory is reserved for 63 zero calibrations and 63 span calibrations. Zero and span calibration records are accessed on the Sensor Calibration History page.
Part 4 – Operation Model F12/D Gas Transmitter Sensor Auto-test Auto-test verifies the serviceability of the sensor on a prescribed schedule by exposing it to a small amount of gas, and verifying a minimum response. Three attempts per test are made, and if the sensor does not respond on the third attempt, a temporary trouble alarm is triggered (may be optionally disabled).
