Send: o3
Receive: o3 6720E-2 ppb
flow a
flow b
These commands report the sample flow in Cell A and Cell B. The example
that follows reports that the current sample flow in Cell A is 0.608
liters/minute.
Send: flow a
Receive: flow a 0.608 l/m
o3 lamp temp
This reports the current ozonator lamp temperature. The example that
follows reports that the current ozonator temperature is 68.7
°
C.
Send: o3 lamp temp
Receive: o3 lamp temp 068.7 deg C
lamp temp
This reports the current bench lamp temperature. The example that follows
reports that the current bench temperature is 55.2
°
C.
Send: lamp temp
Receive: lamp temp 055.2 deg C
lamp voltage bench
This command reports the bench lamp voltage in volts.
Send: lamp voltage bench
Receive: lamp voltage bench 10.3 V
lamp voltage oz
This command reports the ozonator lamp voltage in volts.
Send: lamp voltage oz
Receive: lamp voltage oz 12.3 V
pres
This reports the current reaction chamber pressure. The first pressure
reading is the pressure reading being used in instrument calculations. The
second pressure is the actual pressure reading being measured. If pressure
compensation is on, then both pressure readings are the same. If pressure
compensation is off, a pressure of 760 mm Hg is used as the default pressure
even though the actual pressure is 753.4 mm Hg. The example that follows
shows that actual reaction chamber pressure is 753.4 mm Hg.
