4. Programmable Register Overview
All M2110P Smart Pressure Gauges have programmable registers that allow the gauge to be configured to fit
the pressure measurement application. Programmable registers are numbered P0 through P8. Each register
controls a specific aspect of the gauge’s performance.
A description of all programmable registers, and step by step instructions for their use, is included below. Each
register is found on all M2110 series models, and performs the same function described for all models, except
as noted otherwise.
Px Name Description Value Range Notes
P0
Lockout Code Lockout for security. 00 to 99 00 = Disabled.
P1 Timeout Automatic shutoff in minutes of keypad
inactivity. 0 (disabled), 1, 2, 5,
10, 15, 25 Battery model only.
P2
Damp Rate Exponential damping time in seconds. 0.1, 0.2, 0.5, 1, 2, 5,
10, 15, 25, 50 0.1 = No Damping.
P3
Density of Water
Reference
Temperature Sets reference temperature for water
density when gauge is set for water
column units. 20°C, 4°C, or 60°F
