5.5.2 Zero procedure
To zero the flowmeter, refer to the procedures shown in Figures 5-3 through 5-6. Note the following:
• The zero button is available only on Model 1500 or Model 2500 transmitters. It is located on
the front panel of the transmitter. To press the zero button, use a fine-pointed object that will fit
into the opening (0.14 in [3.5 mm]). Hold the button down until the status LED begins to flash
yellow.
• If the off-line menu has been disabled, you will not be able to zero the transmitter with the
display.
• You cannot change the zero time with the zero button or the display. If you need to change the
zero time, you must use the Communicator or ProLink II.
