Zero Function
When is pushed, the Product zeros its active display if a pressure mode is selected,
and the pressure is within the zero limit. 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. is only used for pressure.
Internal Sensor and Pressure Module (non-absolute)
When a sensor or pressure module is selected on the active display and 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.
Absolute Pressure
When an absolute pressure range is selected on the active display and is pushed, the
Product prompts you to enter the barometric reference pressure. Record the barometric
reference pressure with the arrow buttons. While you do this procedure, make sure the
sensor port is open (vented) to the atmosphere. See Figure 11.
