11.1 Gas Temperature Measurement with Optional Temperature Probe
Connect the temperature probe to the Comms port at the top of the instrument.
Locate a suitable gland or bung on the pipework and insert the temperature probe.
When the probe is as far into the gland as possible without opening the tap, open the gas tap.
Finally, push the probe into the gland far enough to ensure that the tip is in the centre of the gas pipe.
Now press the “Sample” key to begin measuring the temperature in the pipe.
When the reading has stabilised, press the “Sample” key to retain the reading. This will return the highlight area
around the temperature figure. The temperature probe can now be removed from the pipe.
11.2 DIP Meter Reading
The DIP Level function on the GFM436 allows two DIP level readings - DIP1 and DIP2 - to be entered and stored for
each location ID.
To change the DIP Level, select the field and press OK. Then use the Left and Right Key to highlight the digit to be
changed and use the Up and Down Keys to increment or decrement that number. To move to the next digit use the
arrow key.
Once you have finished entering the DIP reading press the OK Key to deselect that DIP level. The DIP level will be
saved on exiting the display but switching the instrument off without exiting the display may cause entered data to
be lost.
Pressing the Left Key will navigate to the Velocity Display and pressing the Right Key will navigate to the Summary
Display.
Pressing the Left Soft Key, labelled “Store” will bring up the Store Menu Window.
Pressing the Middle Soft Key, labelled “Menu”, will bring up the Data Storage Menu Window.
Pressing the Right Soft Key (Reset), will reset both DIP readings to 0.00m.
IMPORTANT: Take great care when inserting the temperature probe to avoid gas leakage.

IMPORTANT: Take great care when removing the temperature probe. In particular, avoid standing with
your face in direct line with the gland because gas can be expelled at great force.
