• When calibrating the RTD or resistance range of the 6-CH, Medium-Speed Four-Wire
RTD Resistance Input module
Short the input terminal
of CH3 (connect 0 Ω)
When calibrating the RTD (1 mA)
20 mV range, connect 20 Ω to the
input terminal of CH4.*
* When calibrating the RTD (1 mA) 60 mV range, connect 60 Ω to the input terminal of CH5.
When calibrating the RTD (1 mA) 200 mV range, connect 200
Ω to the input terminal of CH6.
When calibrating the RTD (1 mA) 600 mV range, connect 300
Ω to the input terminal of CH4.
When calibrating the RTD (0.25 mA) 600 mV range, connect 2400
Ω to the input terminal of CH5.
When calibrating the RTD (0.25 mA) 1 V range, connect 3000
Ω to the input terminal of CH6.

• When calibrating the range of the 4-CH, Medium-Speed Strain Module (-B12, -B35,
and -NDI)
The clamp terminal (-B12, -B35) and NDIS terminal (-NDI) are connected with the
4-gauge method (see next page). Use a resistance of 120 Ω for resistors R1 through
R3, and connect a resistance to R4 equivalent to the Zero or Full value.
To correctly calibrate the range, do so in the order Zero, then Full.
ZERO FULL
Calibration range Resistors R4 Resistor R4 Resistance value accuracy
ZERO 120.000 Ω 120.000 Ω ±0.005%, ±0.3 ppm/°C
2000 µSTR 120.000 Ω 117.154 Ω ±0.005%, ±0.3 ppm/°C
20000 µSTR 120.000 Ω 113.010 Ω ±0.005%, ±0.3 ppm/°C
200000 µSTR 120.000 Ω 80.000 Ω ±0.005%, ±0.3 ppm/°C
* The Full calibration value of the 2000 µStrain range is equivalent to 12000 µStrain
The Full calibration value of the 20000 µStrain range is equivalent to 30000 µStrain
The Full calibration value of the 200000 µStrain range is equivalent to 200000 µStrain
