* Since the power supply frequency noise is not rejected, the measured vales may fluctuate. In such
cases, set the measurement interval to 200 ms or higher.
Gauge connection method:
1-gauge (2 or 3 wire systems), opposing 2-gauge, adjacent 2- or
4-gauge
With clamp terminals, set on a channel basis with switches
Applicable gauge resistance:
100-1000 Ω
Built in resistance of 120 Ω for -B12, and 350 Ω for -B35.
Bridge voltage: Fixed at 2 VDC, accuracy ±5%, compensated with internal Cal
Applicable gauge factor: Fixed at 2.0. Gauge factor can be compensated with the scaling
function.
Balance adjustment: Automatic, digital calculation methods
Balance adjustment range: ±10000 µstrain (1-gauge method conversion)
Balance adjustment accuracy: The measurement accuracy or less:
Resistance accuracy for bridge: ±0.01% ±5ppm/°C
Input resistance:
1 MΩ or more
Allowable wiring resistance: 100 Ω or less
Effect of wiring resistance: NDIS 50 ppm of rdg/Ω (when using remote sensing wire).
Does not compensate for clamp wiring resistance. Depends on
the gauge resistance.
