5.3 Turning the Output On and Off
Procedure
Flip the
OUTPUT
switch up.
• The output turns on. The OFF indicator turns off, and the ON indicator turns on.
• Flipping the OUTPUT switch down while the output is on will turn off the output. The ON indicator will
turn off, and the OFF indicator will turn on.

Output terminals
Note
• When outputting current, do not open the output terminals.
When outputting voltage, do not short the output terminals.
In either case, the overload protection function will be activated, an error code will be displayed, and the
output will be turned off. The time it takes for the error to appear depends on the range and output value.
• If the output terminal temperature changes as a result of making contact with the lead wires, crimping
terminals, banana plugs, or other conductors during wiring or due to ambient air movement, errors
exceeding the accuracy specifications may occur when a small output range is used. In such situations,
wait until the output stabilizes. Also while the 2553A is generating output, keep the output terminal
temperature from changing due to the effects air conditioning, other heat sources, and the like.
Explanation
Turning the Output On and Off
When the output is turned on, the 2553A will source the specified voltage, current, or resistance from
the output terminals.
• If you change the range setting, the output automatically turns off.
• If the output setting is outside the selectable range, the output cannot be turned on.
