c signal and cold end mode: 20mV / 100mV / 4-20mA / PT100 / Ω / K / E / J / T / R / B / S / N. RJA is the automatic cold end and M is the manual cold end.
d programming function: n / m is divided output, output value = (main setting value) * (n / m)
The sweep is a linear output, which outputs the signal according to the time set by the user.
Step is the step output, and the step output signal is set by the user.
Time is the output time of each step, 0-999S can be grouped.
Count is the number of output cycles, 0-999 times can be grouped, and 0 is infinite cycle.
