Instrument Mode
Holds code for current mode of instrument. Possible working modes of instrument are
listed below.
$0001 Normal
$0002 Calibration
$0003 Warm-up
$0006 Zeroing
$0008 Fault
$0009 Reset
Examples:
Sensor in zero fault = $0008
Sensor zeroing = $0006
40106 W R $0000 to $FFFF
Status Bits
Holds 16 bits of status for various parameters in the instrument. A bit value of “1”
indicates that the associated fault condition is present.
Bit 15 = current loop open
Bit 14 = current loop shorted
Bit 13 = power fault
Bit 12 = 5 volt fault
Bit 11 = missing sensor
Bit 10 =
(not defined)
Bit 6 = configuration fault
Bit 5 = zero fault
Bit 4 = calibration fault
Bit 3 = over-range
Bit 2 = failed sensor
Bit 1 = high alarm
Bit 0 = low alarm
Examples:
Missing sensor = Bit 11 is set = $0800
Power fault and
failed sensor = Bits 13 and 2 set= $2004
40115 W R
Last Alarm Date (mmdd)
Holds the month and day when the instrument had the last alarm.
High byte = $01 to $0C
Low byte = $01 to $1F
