Voltage Current
–11.000 V 0.000 mA –22000
–10.000 V 0.000 mA –20000
0.000 V 0.000 mA 0
1.000 V 4.000 mA 2000
5.000 V 20.000 mA 10000
5.500 V 22.000 mA 11000
10.000 V 25.000 mA* 20000
11.000 V 25.000 mA* 22000
* Value in calculation. Actually, the value is clipped at approximately 22 mA.
Output Span Setting
Span setting data when setting transmission output
• V mode
Output voltage [V] –10.000 10.000
PC data* –10000 10000
* PC data refers to internal data between the PC and MX100 main unit, and on the PC
software, the output value is expressed in the same manner with 3 digits after the decimal
point.
• mA mode
Output voltage [mA] 0.000 20.000
PC data* 0 20000
* PC data refers to internal data between the PC and MX100 main unit, and on the PC
software, the output value is expressed in the same manner with 3 digits after the decimal
point.
• Limit value of V mode and mA mode

upper limit *2
V mode –11 [V] –10 [V] +10 [V] +11 [V]
mA mode 0 [mA] 0 [mA] 20 [mA] 22 [mA]
*1 –OVER, preset value
*2 +OVER, preset value
Handling Abnormal Data
Types of Abnormal Data Output Values
Output data upon startup Preset value or previously held value can be selected
Data upon error occurrence Preset value or previously held value can be selected
+OVER 5% of output Full Span
–OVER –5% of output Full Span
±OVER determination
For user output, ±OVER determination is performed on the PC, and if the limit value is
exceeded, it is clipped at that limit value. For transmission output within the same unit,
OVER is determined by the MX100 main unit.
±OVER conditions
• When the input channel is ±OVER in the case of transmission output
• When outside the range of ±5% of output Full Span
• When outside the range of voltge –11 V to +11 V, or current 0 mA to 22 mA (accuracy
assured at 1 mA or more)
