TSI Instruments 4000 Series User Manual

53
Use the SAVE command to permanently store the selected flow units
as the new power-on default.
Example 1) SUS Selects units of Std L/min for flow rate
SPnnn.nn
Sets the pressure to be used for internal pressure compensation and
for conversion from standard L/min to volumetric L/min. The unit will
default to 101.3 kPa on power up.
SP Denotes Set Pressure.
nnn.nn Denotes pressure in kPa.
For units with an analog pressure input, setting this SP parameter to
0 kPa will enable the analog pressure input.
The SAVE command will only save whether the analog pressure
input is enabled or disabled. The unit will always power up either with
analog pressure input enabled or to the default value of 101.3 kPa.
Example 1) SP108.00 Sets pressure value for calculation to 108.00
kPa
Example 2) SP000.00 Enables analog pressure input
