Command Description
F
"F2000" sets flow rate to 2000 pl/s. Replies
"#F0" and starts flow control if in remote control
(Not
mode (see A1). For this command to work there
available
must be a flow sensor connected either via USB
in P-Pump
(3200095) or I2C (3200200) connection on the
version 1)
back of the pump.
Note "F0" is a valid flow target and does not set
the pump to IDLE!
Rx
Tares pump and/or connected flow sensor and
drops back to idle when completed. Pump must
be in remote mode.
x selects the tare options:
0 pressure and flow (if present);
1 pressure only;
2 flow only (if present).
The pump MUST be disconnected from the
pressure supply to tare or an ERROR is raised.
The pump will enter TARE state (see TARE) on receiving this command and attempt to tare. On
completion (some number of seconds later), the pump will re-enter IDLE state. If the tare fails
an error is raised. You should monitor the pump state during tare using "s".
v
Replies with the version of pump firmware, e.g.
"#v1.0.48"
Get the current maximum and minimum target
m
ranges from pump. Replies with "#mxxx,yyy"
where xxx is the max and yyy is the minimum (in
mbar).
K
Perform leak tests (does leak test twice, once at
high pressure and once at low pressure)
You must have a pressure supply connected. For the leak test results to be meaningful, a 30ml
chamber volume (or equivalent) should be connected to the pump. The pump will enter LEAK
TEST and when leak test completes (about one minute) the pump will re-enter IDLE state.
k
Get leak test data result from pump.
Replies with "#kxxxxxxxx,yyyyyyyy"
Where xxxxxxxx and yyyyyyyy are each signed 4 byte integers. High two bytes are pressure
change (in mbar/bar/minute, positive or negative) and the lower two bytes are a pass/fail flag
(high/sign bit, 0 is pass, 1 is fail) plus the test pressure (in mbar). See below for an example of
how to extract these numbers. These values are invalid if an error occurs during the leak test or
if the value is 0x8000.
e.g. Response is #k-2941957,-2517092
-2941957 = 0xFFFB 823F3.
-2517092 = 0xFFD9 979C.
3600051 - P-Pump API - programming instructions - v 1.3
0xFFFB = -5 mbar/bar/min
0x82F3 = 0x8000 (fail flag bit) plus 0x02F3 = 755mbar.
0xFFD9 = -39mbar/bar/min
