Comparator function
The comparator function refers to the function of comparing pre-set critical values
with measured values, determining whether the measured values meet the
judgment criteria, and displaying and outputting them. The comparison methods
for thresholds include two methods: setting upper and lower limits, and setting
baseline values and percentages. As a comparator result, in addition to displaying
Hi, In, Lo pages and sounding the buzzer, it can also be output through the EXT
I/O terminal.
There are two comparison modes: Auto and Manual, with the default being Auto
mode.
Automatic mode: After setting to automatic mode and enabling the comparator
function, always output the comparison results of the comparator.
Manual mode: After setting to manual mode and enabling the comparator
function, the comparison result is only output when the MANU input of EXT I/O is
on.
Note:
When the comparator is turned on, automatic range cannot be used.
