- Binary (High Byte/Low Byte),
and
3
- Counts (ASCII).
F?
Query the data format.
F#
Set Burst Mode
Frequency
F#freq
Select burst mode sampling frequency where
freq
is a real
number and where
38.5
<
freq
<
20000.0
Hertz (default).
G
Calibrate Channel Gain
Gchan,
type
Calibrate the correction gain constants for given option card where
chan
is the channel number such that
1
<
chan
<
max
,
where
max = 128
for NetScan.
The chassis is
chan = 0
.
type
is the channel type.
H
Calibrate Channel
Offset

for NetScan.
The chassis is
chan = 0
.
I
Set Scan Interval
Inorm, acq
Set the two configurable scan intervals of the unit where
norm
and
acq
are the normal and acquisition scan intervals which
have the form:
hh:mm:ss.t
where
hh
is hours,
mm
is
minutes,
ss
is seconds, and
t
is tenths of a second.
I?
Query scan interval selection.
I#
Digital Input Stamping
I#state
Specify whether or not digital input stamping will be enabled.
state
may have either of the following values: The default of
0
, which disables digital input stamping, or
1
to enable digital
stamping.
J
Calibrate Cold Junction
Offset
Jchan,
type,
temp
Calibrate the cold-junction offsets for cold-junction compensation
of the thermocouple signals where
chan
is the channel number
such that
1
<
chan
<
max
,
where
max = 128
for NetScan.
type
is the thermocouple channel type.
temp
is the reference temperature currently being applied to the
selected channel, with the form
nnn.n
in degrees
º
C.
K
Enter Calibration Mode
Kkey
Enter Calibration Mode if the keyword (or password) is correct,
where
key
is the keyword in the form of a 5-digit number
nnnnn
. Therefore the password can be no longer than 5
characters.
K?
Query
Kkey
as defined above.
