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
P4 User Units
Full Scale Enables gauge to display units other
than factory defined Engineering Units.
0 to 9,999 (Keypad)
0 to 19,999 (Serial)
User defined value.
SetPoint Model: defines which relay
outputs are active. 0 = Disabled.
1 = SET1 only.
2 = SET2 only.
3 = Both enabled. P5 SetPoint Options
Current Loop Model: defines the status
of the 4 - 20 mA output. 0 = 4-20 disabled
1 = 4-20 enabled
Not found on
Battery model.
P6 SET1 Controls SET1 relay or 4.00 mA value. –20% to +120% FS User defined value.
P7 SET2 Controls SET2 relay or 20.0 mA value. –20% to +120% FS User defined value.
P8 Deadband Sets the amount of deadband in percent
of full scale for relays. 0 (disabled), 0.1,
0.2, 0.5, 1, 2, 5, 10% SetPoint model
only.
