Martel Electronics BetaGauge PI PRO - Manual (Page 7)

The tare value is set manually with the
▲ and ▼ keys, and is
based on the engineering units and resolution selected for display.
TARE value can be set to the maximum range of the gauge.
The bar graph will always display the actual pressure based on the
full range of the gauge regardless of the tare setting. This is done
for safety to insure that even with a “0” reading that pressure is
being applied to the gauge.
8. Function Lock: Access to each of the settable parameters above
can be turned “off” once set, to prevent unauthorized changes to
configuration. This is accomplished through a password protected
“supervisory mode”. Press ENTER to access the supervisory
mode, or CONFIG to return to normal operation.
4. Supervisory Mode
Press ENTER when “FUnC LOCK” is displayed, 0PWRD will be
displayed on the gauge. The password to enter supervisory mode is
101, set using the
▲ and ▼ keys. Holding a key continuously will
cause the display to advance more quickly for faster setting. The
password is factory set and cannot be changed
1. Your BetaGauge PI is shipped from the factory with all setting
access “unlocked” or available to be changed.
2. In supervisory mode each of the parameters can be locked or
unlocked using the
▲ and ▼ keys. Select LOC (lock) for those
parameters you do not want to be accessible, and UnLOC (unlock)
for those can be accessed.
3. In order, the functions that can be unlocked, locked or accessed
are:
• Zero function (enable/disable)
• Set pressure units (enable/disable)
• Auto shutdown adjustment (enable/disable)
• Damping settings (enable/disable)
• Sample rate setting (enable/disable)
• Tare setting (enable/disable)
• Custom engineering units (set scale factor)
4. Use the CONFIG key to scroll through the above choices, and the
▲ and ▼ keys to lock and unlock features. Press CONFIG to
continue scrolling through the parameters, pressing ENTER at any
point saves your settings and returns the gauge to normal
operation.
When a function is “locked, it cannot be accessed or changed
from its current state. To change a locked function, enter the
supervisory mode, and unlock the function. Once it is changed,
you may enter supervisory mode to lock access again.
