2.2 Characteristics
Linearity (when using kaolin standard):
Upper range limit of 1000 mg/l (degrees) or less: ±2% of full scale
Upper range limit of 2000 mg/l (degrees) or less: ±5% of full scale
When the lower range value is a value other than 0 mg/l (degree),
the full scale should be interpreted as the upper range limit.
Linearity (when using polystyrene latex standard):
Upper range limit of 100 mg/l or less: ±2% of full scale
Upper range limit of 2000 mg/l or less: ±5% of full scale
Repeatability:
Standard solution: 2% of full scale
Calibration plate: 1% of full scale
Effect of Power Supply Voltage: Within ±1% of full scale/±10% of rated voltage
Effect of Ambient Temperature: ±1% of full scale/10 °C (calibration plate)
Response Time:
Within 2 minutes (90% response, with sampling system, at a fl ow rate of 3
l/min)
Warm-up Time: Approx. 30 minutes
