OUTPUT SPECIFICATIONS
■ DC Current
Output range: 0 – 20 mA DC
CALCULATION EXAMPLES OF OVERALL ACCURACY
[Example] Total Resistance 1000 Ω, Input Setting 100 – 600
Ω, Output Range 0 – 20 mA, Output Setting 4 – 20 mA,
Segment Gain 1.5
Conformance range: 0 – 21mA DC
Minimum span: 1 mA
Load resistance: Output drive 15 V max.
(e.g. 4 – 20 mA: 750 Ω [15 V ÷ 20 mA])
(Not available to output less than 0 mA, output range may
not be extended to -5 %)
■ Overall accuracy
• Input Accuracy = Total Resistance (1000 Ω) ÷ Input Span
Setting (500 Ω) × 0.03 % = 0.06 %
■ DC Voltage
Less than 1 Ω thus 1 Ω (0.1%) is selected.
• Output Accuracy = Output Range Span (20 mA) ÷ Output
Span Setting (16 mA) × 0.06 % × Segment Gain (1.5) =
0.1125 %
Output range: -5 - +5 V DC, -10 - +10 V DC
Conformance range: -5.5 - +5.5 V DC, -11 - +11 V DC
Minimum span: 250 mV, 1 V
Load resistance: 200 kΩ min.
Overall Accuracy = 0.1 + 0.1125 = ±0.2125 %

FUNCTION
Indicates present values, setting values and abnormal information.
Two types of present values are displayed respectively at the upper and lower parts according to setting.
Mode button
Set button
Shifts from Measuring mode to each setting mode.
The destination changes depending on how long the button is held down.
Pressing Mode button for ≥ 2 seconds returns to Measuring mode from each setting mode..
Shifts the setting value of each setting parameter item to a setting changeable state.
When at setting changeable state, used to move through the digits of setting value and to enter (save) the
setting value.
Up button
Shifts through setting parameter items and to increase or select the setting value.
Shifts through setting parameter items and to decrease or select the setting value.
Down button
Congurator Jack
Used to perform conguration with M1E congurator software (model: M1ECFG).
When using the software, set the Lockout setting of the unit to ‘Lock’.
Refer to the operating manual (EM-5983-B) for detailed procedures.
