* Settings of 1 to 30000 ms (1 ms range) and 10 to 30000 ms (10 ms range) are allowed, but the setting
command is specified as a multiple of the output range. Refer to the AO command in section 1.4.
Note
For information on the measurement accuracy at each measuring range, see the MW100 Data
Acquisition Unit User’s Manual (IM MW100-01E).
Upper and Lower Limit of Span (MATH Channels)
Set the mantissa between –9999999 and 99999999. Set the decimal place in the range
from 0 to 4.
Upper and Lower Limit of Scaling
Set between –30000 and 30000. Set the decimal place in the range from 0 to 4.

Alarm Value Setting Range
The following shows the setting ranges for alarm values.
Measurement Channels
Alarm Type Computation Type Alarm Value Setting Range
H/L OFF/DELTA/RRJC Normal mode span setting range
SCALE Scale Low to High limit (low limit < high limit)
Scale High to Low limit (high limit < low limit)
DH/DL DELTA Difference mode span setting range
RH/RL OFF/DELTA/RRJC 1 to width of normal mode span setting range
SCALE 1 to width of scale upper/lower limit values
TH/TL OFF/DELTA/RRJC Normal mode span setting range
SCALE Scale Low to High limit (low limit < high limit)
Scale High to Low limit (high limit < low limit)
MATH Channels
Within the MATH channels span range (–9999999 to 9999999 (mantissa))
Hysteresis Value Setting Range
The following shows the setting ranges for hysteresis values. The set hysteresis does not
apply to the upper/lower limit on rate-of-change alarm.
Alarm Type Hysteresis Value Setting Range
H/DH/TH 0 to (alarm value – alarm value setting range lower limit)
L/DL/TL 0 to (alarm value setting range upper limit – alarm value)
