Select the Temperature Rotary Dial position.
WARNING
Never attempt to take a pressure reading without knowing the maximum pressure that might be present.
This instrument's pressure transducer is rated at 2.3in H
Using the black connectors and the manometer hose. Connect P1 for a single pressure or P1 and P2 for differential pressure.

WARNING
Before using the analyzer to measure the pressure of a gas/air ratio valve, read the boiler manufacturer's manual thoroughly. If in
doubt, contact the boiler manufacturer. After adjusting a gas/air ratio valve, it is essential the CO, CO2, CO/CO2 ratio readings are with-
in the boiler manufacturer's specified limits.
If using larger bore tubing when performing pressure tests:
C161
Push tubing over the rim of the
spigot to ensure a gas tight seal.
TEMPERATURE TESTING
Use the T1 connection for the Flue Probe temperature sensor
Use the T2 connection for the Inlet temperature sensor
Real time temperature difference
Real time pressure reading (pressure will only show is fitted)
PRESSURE TESTING
0 with a maximum pressure over range of 11.8in H
2
Use the T1 connection for the Flue Probe temperature sensor
Use the T2 connection for the Inlet temperature sensor
Real time temperature difference
Real time pressure reading (pressure will only show is fitted)
PRESSURE MEASUREMENT GOOD PRACTICE
LARGE BORE TUBING ISSUES
This may not produce a gas tight seal.
