Command List
Lasair II Particle Counter Operations Manual Page G-7
GALARM [1/0] Enable or disable global alarm setting. When disabled, all alarms
are off. When enabled, individual alarm settings are in effect.
ID cccccccccc Set instrument identification using maximum of 16
characters.
ISAVAIL Check if instrument control is available. The Lasair II particle counter
has multiple methods of communications, as well as the front panel control. To
prevent confusion, only one user is allowed to control the instrument at a time. This
command will return a 0 if the serial communications is unable to take control of
the instrument. This can be used as a check if an error occurs while executing
another command. Using the KB or KG commands ensures that the serial
communications will have control of the instrument.
ISDELAY secs Set inter-sample delay. This is the delay between the end of one
sample, and the start of the next. The maximum value is 86399 seconds (23:59:59).
ISON Return the sampling state of the box (1/0).
ITYPE Return the instrument model.
IVER Return the instrument firmware version.
KB [1/0] Keypad lockout enable/disable. Lockout is retained through a power
cycle. If this lockout is disabled with the “KG 0” command, it will be re-enabled
when the power is cycled.
KG [1/0] Keypad lockout enable/disable. Lockout lasts until “KG 0”, “KB 0”,
or a power cycle
LOCID name If needed, creates and sets the current location ID to name. If name
already exists, the front panel screen will change the ID. If the name does not exist,
and there are less than 200 names currently defined, then the new name will be
created, and the current location will be set to this string. If the instrument is taking
a sample, this command will return an error. This command is used to facilitate an
interface to a barcode reader.
NORMDATA [1/0]
Set normalized/raw particle display. If particle display is set to 0, then data is shown
in raw counts on the display. In addition, if particle alarms are used, the alarms
automatically change with sample time changes.
PALARM chan,value,[1/0] Set particle alarm for specified channel. Channel
is 1–6. Alarm value is any number greater than or equal to 0. Note: if value is set to
0, channel must be disabled. An error will be returned if setting is to enable a
channel with 0 as the value.
