ZERO BUTTON OPTIONS
Use the Zero button options to adjust the pressure the gauge reads as zero.
•
Zero Limit:
By default, all gauges come pre-programmed with a 20 psi maximum zero limit. This means that you can apply pressure (up to 20 psi) to the
gauge, press the
(
zero
)
button, and the gauge will read zero. In some situations it may be desirable to increase or decrease the maximum pressure that the
gauge could be set to read zero pressure. It’s also possible to disable the
(
zero
)
button entirely by setting a zero Limit of negative (-)15 psi.
•
Enable TARE:
Enabling the TARE mode allows the second line to display a tare value (instead of forcing the display to read zero at an elevated pressure). This
applies to dual line display (-DD) models only. Not available on all -DD models.
—
ENABLE VACUUM MODE
Only available on DP gauges, this sets the gauge into Vacuum Mode. When working with vacuum, the vacuum pressure should be applied to the – (vacuum)
port of the DP gauge. However, when applying vacuum to the – port, it creates a positive diff erential pressure, and therefore will display a positive pressure on
the gauge. By enabling Vacuum Mode, the reading on the gauge will properly display a negative pressure value when applying vacuum.
