4. Operations
4.1. Power Up
There are two power up modes. The unit will either immediately begin running in the
previous sample mode, or will immediately send a ‘>’ character, and wait for a
command. There needs to be a delay of at least 500ms before sending the first
command. In both cases, the data format will remain as that previously used.
#092<enter>
Reads start up mode
#091;ON<enter>
Readings at last rate at start up
#091;OFF<enter>
No readings at start up
4.2. Stop Command
The unit can be stopped at any time by sending the ‘#’ character. The unit returns a ‘>’,
and waits for a further command.
4.3. Command Echoes
Each command character is immediately echoed back
<Enter> is echoed back as <cr><lf>
4.4. Pressure Format Commands
#083;0
Turns pressure sensor off and unit reverts to SV only operation mode
#083;1
Sets pressure data format to 1 decimal place
#083;2
Sets pressure data format to 2 decimal places
#083;3
Sets pressure data format to 3 decimal places
#018;0
Sets units to dBar
#018;1
Sets units to Metres
#018;2
Sets units to Feet
#019
Read Pressure Units
4.5. Pressure Tare Commands
#011;on
Turns Tare mode on (i.e. unit subtracts fixed value from pressure data)
#011;off
Turns Tare mode off (i.e. unit outputs pressure as read)
#009;
Unit takes single pressure reading to use as Tare value.
#009;0
Sets Tare value to zero (i.e. removes tare)
#009;
{value}
Input Tare value in units of 0.001dBar (i.e. 9000 = 9dBar)
