Zero Function Use; Internal Sensor And Pressure Module (Non-Absolute); Absolute Pressure - Fluke 719PRO User Manual

Zero Function Use

If a pressure mode is selected and pressure is within the
zero limit, the Product zeros the active display when Z is
pushed. The zero limits are within 10 % of the full-scale
range of the selected sensor. If the display shows "OL,"
the zero function will not operate.
Z is only used for pressure.
Internal Sensor and Pressure Module (non-
absolute)
When a sensor or module is selected on the active
display, and Z is pushed, the Product subtracts the
current reading from the output. The zero limits are within
10 % of the full-scale range of the selected sensor. If the
display shows "OL," the zero function will not operate.
Note

Absolute Pressure

When an absolute pressure range is selected on the
active display, and Z is pushed, the Product prompts for
the barometric reference pressure as in the screen below.
Push  and  to use the on-screen arrows to record the
correct barometric reference pressure. The sensor port
should be open (vented) to atmosphere while this
procedure is done.
