p5 Hold/Not hold the relay
HOLD Hold the relay output until an
alarm acknowledge operation is
executed
NONHOLD Reset the relay output when the
alarm is cleared.
p6 Hold/Not hold the alarm status display
HOLD Hold the display until an alarm
acknowledge operation is
executed
NONHOLD Clear the display output when

p7 Interval for the high limit on rate-of-change
alarm (01 to 15)
p8 Interval for the low limit on rate-of-change
alarm (01 to 15)
p9 Alarm hysteresis on measurement channels
(OFF, 0.1%, 0.2%, 0.3%, 0.4%, 0.5%, 0.6%,
0.7%, 0.8%, 0.9%, or 1.0%)
p10 Alarm hysteresis on computation channels

Example Enable fault diagnosis output. Disable reflash
and AND operations. Set the relay operation
to energize and hold. Set the alarm status
display to hold. Set the interval for the high limit
of rate-of-change alarm to 10, the interval for
the low limit of rate-of-change alarm to 12, the
measurement alarm hysteresis to 0.5%, and the
computation alarm hysteresis to OFF.

Description • The interval for the high limit of rate-of-change
alarm is equal to “scan interval × p7” and
the interval for the low limit of rate-of-change
alarm is equal to “scan interval × p8.”
• Parameter p10 can be specified on models
with the computation function (/M1 option).
• For the details on the settings, see the
µR10000 Recorder User’s Manual or the
µR20000 Recorder User’s Manual.
XI Sets the A/D integral time.
Syntax XI p1<terminator>
p1 Integration time of the A/D converter
AUTO Automatically set in synch with
the power supply frequency.
50HZ 20 ms
60HZ 16.7 ms
100MS 100 ms (dot model)
Query XI?
Example Set the A/D integral time to 50 Hz.
XI50HZ
Description • 100 ms is available only on the dot model.
• If Auto is specified when using the 24-VDC
power supply on a recorder with the 24-VDC/
AC power supply (/P1 option), the integration
time is fixed to 20 ms (50 Hz).
XB Sets the burnout detection.
Syntax XB p1,p2<terminator>
p1 Channel number
p2 The procedure taken when a sensor burnout
is detected
OFF Disable the burnout detection.
UP
Set the recording off the scale to the
right when a burnout is detected.
DOWN Set the recording off the scale to the
left when a burnout is detected.
Query XB[p1]?
Example Set the recording off the scale to the right when a
sensor burnout is detected on channel 01.

XJ Sets the RJC.
When using the internal compensation circuit
Syntax XJ p1,p2<terminator>
p1 Channel number
p2 Reference junction compensation selection
(INTERNAL)
Query XJ[p1]?
Example Use the internal compensation circuit on channel
01.
XJ01,INTERNAL
When using an external RJC
Syntax XJ p1,p2,p3<terminator>
p1 Channel number
p2 Reference junction compensation selection
(EXTERNAL)
p3 Compensation voltage (–20000 to 20000)
[µV]
Query XJ[p1]?
Example Set the reference junction compensation of
channel 02 to external and set the compensation
voltage to 0 µV.
