Measuring accuracy in case of scaling (digits)
Accuracy during scaling (digits) = measuring accuracy (digits) × multiplier + 2 digits (rounded up)
where the multiplier = scaling span (digits)/measuring span (digits).
Example: Assuming that
• range: 6 V
• measuring span: 1.000 to 5.000 V
• scaling span: 0.000 to 2.000
Then,
Measuring accuracy = ±(0.1% × 5 V + 2 digits) = ±(0.005 V [5 digits] + 2) = ±(7 digits)
Multiplier = 2000 digits (0.000 to 2.000)/4000 digits (1.000 to 5.000 V) = 0.5
Accuracy during scaling = 7 digits × 0.5 + 2 = 6 digits (rounded up)
Reference junction compensation
Internal/External selectable for each channel
Reference junction compensation accuracy (above 0°C):
When the temperture of the input terminal is even (60 minutes or more after power on)
