Note 1 Factory set value varies depending on the instrument specification. However, factory set value
of a case of voltage input is 100.0 (high limit) and 0.0 (low limit).
Note 2 Factory set value varies depending on the input type.
Note 3 Factory set value varies depending on the instrument specification. However, factory set value
of a case of voltage input is 1.
Note 4 CTL-6-P-N: 800
CTL-12-S56-10L-N: 1000
Note 5 TC and RTD inputs: 2 °C [°F] or 2.0 °C [°F]
Voltage input: 0.2 % of span
