B 310
Q = Set APC in stand by, (stop a measurement)
Returns a “Q”.
R = Activates probe 0 (built in P50 driver)
Returns an “R”.
S = Activates probe 1 (Installed probe driver)
Returns an “S”.
X = Shift State to "Analysis Mode"
Returns nothing.
Z = Shift State to "Detection Mode"
Returns nothing.
Y = Shift State to “Combined Mode”
Return nothing.
Supported parameters
The following parameters can be downloaded to Sensistor ISH2000 in Analysis
and Detection mode.
Where: “Header” + “?” returns the a value from the instrument. This value is
presented as “A”, “B” and so on.
* entered as integer in 10’s of seconds, 1= 0.1s, 100 = 10s, 60000= 6000s
Default listed unit
PPM, cc/s, cc/min, SCCM, g/a, oz/yr, mbarl/s, mm3/s, mm3/min, Pa m3/s
Transfer of parameters
Send parameters one by one; send the specific header and then send the data
(for example “1.00E+01”). String must be ended with a carriage return charac-
ter, chr13 (dec).
Example: “CPPM” or “C PPM”, Carriage Return (chr 13). This sets Reject Level
Rate Unit to “PPM”.
