7.1.11 Synchronization of Input Sampling
The synchronization accuracy of input sampling is less than ±100 μ s.
In a daisy chain connection, input sampling between units can be synchronized.
In a connection other than a daisy chain, input sampling between units cannot be kept
synchronized though input sampling in each individual unit can be kept synchronized.
7.1.12 RJC (Reference Junction Compensation)
This function is enabled with firmware version R1.02.01 or later.
If thermocouple input is selected, RJC can be turned OFF/ON.
Normally, input compensation is performed using the VZ20X RJC function. However, the
VZ20X RJC function can be turned OFF in order to use a zero controller or other
external device to perform strict compensation.
7.1.13 ERJC (External Reference Junction Compensation)
This function is enabled with firmware version R1.02.01 or later.
During thermocouple input, a temperature compensation value can be set on an
external device.
However, this is enabled only when RJC is OFF.
Type B external reference junction compensation is fixed to 0°C.
