*3 If the judgment value is correct, the parameter range is
from - 999.97 to +999.98 (percent mode).
from - 99.997 to +99.998 (size mode).
If the current value is over range, under range, or invalid, the previous value is retained
without updating the current value. Use the value with the judgment value property.
*4 If the read data has one of the values listed below, it has a different meaning than
the judgment value.
In % mode:
+999.99: The value is above the upper limit of the display range.
-999.99: The value is -999.98 or below the lower limit of the display range.
-999.98: The value is "-----" (invalid).
+1000.00: The sensor amplifier is in error.
In size mode:
+99.999: The value is above the upper limit of the display range.
-99.999: The value is -99.998 or below the lower limit of the display range.
-99.998: The value is "-----" (invalid).
+100.000: The sensor amplifier is in error.
*5 When in sample hold:
Value "-99.998" is output.
When not in sample hold:
The peak value encountered during the sampling period is output.
*6 When in sample hold:
Value "-99.998" is output.
When not in sample hold:
The bottom value encountered during the sampling period is output.
*7 When reading data from an amplifier unit in which the measurement mode is to "size
mode", the data format changes to "±**.***" (the read range is -99.999 to +99.999").
*8 If the sensor amplifier is in error, the analog voltage output is +5.500 and the analog
current output is +03.00.
*9 If a prohibited combination of functions is written, it results in "abnormal setting (1)"
For details of each function, refer to the IB Series User's Manual.
