Explanation
Turning the Comparator Function ON/OFF
After having set all the items described on the previous pages, turn the comparator
function ON.
• on: The comparator function will start by pressing the ENTER key after selecting “on”;
• oFF: The comparator function will stop by pressing the ENTER key after selecting “oFF.”
CAUTION
• After having turned ON the comparator function, do not change the comparator mode.
Changing the type of limit might result in unexpected statuses of the output relay.
• Make sure not to greatly vary the input signal before turning the comparator function
ON. Depending on the input signal used for determination, the instrument may display
error codes (i.e. overrange) and this will change the output relays as described on page
9-11. When using the output relay as a control signal, make sure to match these
control signals with other equipments to eliminate erroneuous control.
