‘stream??’
o When a sensor is attached to the Instrument and has been zeroed, the Instrument
will output differential pressure readings to the USB port at a rate of 1000 samples
per second.
o Each line of streaming data will contain: a sign for negative values, differential
pressure in 1 count per 0.1 mmHg, a comma separator, a sequence decimal digit,
and two hexadecimal digits that encode a CRC8 value for the previous characters
on the line. Each line is terminated with a carriage return without a line feed.
Some examples are:
x “-1,44a” is -0.1 mmHg with a sequence digit of 4 and CRC8 value of 0x4a.
x “2301,2b8” is 230.1 mmHg with a sequence digit of 2 and a CRC8 value of
0xb8.
o When no sensor is attached, or the sensor has not been zeroed, the Instrument will
not output to the USB port.
o Monitor mode
o The instrument can be changed to monitor mode by typing ‘monitor??’
o The first line of output will be the headings for each column
o Each subsequent line will contain the values, comma separated
o Lines will be output once per second

USE REPLACEMENT
Note: Use the same type and rating of fuses supplied by RJC:
x North America and supplies ~110V 60Hz, use a fuse rated [300mA/t 250V].
x Central Europe and supplies ~220V 50Hz, use the fuses (2 required) rated[315mA/t
250V].
x Japan and suppies ~100V 50/60Hz, use a fuse rated [375mA/t 250V].
o If connected, disconnect power cord-set from AC power module.
o Use a small flat head screwdriver to open fuse holder door on the AC power module
(Figure 1).
o Loosen fuse holder block by rocking back and forth; remove block when loose.
o Remove existing fuse(s) from the block and replace with new one(s). Always replace
fuse(s) with recommended type.
o Reinstall fuse holder block. Note – the fuse(s) that goes into the power module first is
the active fuse(s).
o Close the fuse holder door.

HANGING POWER CONFIGURATION
To change from North American (110 VAC) to European (220 VAC) fusing:
o Use a small flat head screwdriver to open fuse holder door on the AC power module
(Figure 1).
o Loosen fuse holder block by rocking back and forth; remove block when loose.
