7.1 Sweep Function
Step 6: Using the pair of
and
keys, set the upper limit of the
signal to be output. The lower limit is set to a value predeter-
mined depending on the selected range.
Step 7: Pressing the
key initiates sweeping and the output value
begins to increase.
• The LCD shows
and the lower limit (default) for
approximately two seconds. The calibrator outputs the de-
fault.
• Then, the LCD reading and the output value begin to in-
crease in fixed increments, up to the upper limit, in the
sweep time set in the preceding steps.
• When the output reaches the setpoint, the calibrator re-
tains the output as is, and automatically holds sweep op-
eration.
Step 8: Pressing the
key once again causes the output value to
begin decreasing. The output value decreases down to the
lower limit in the same amount of time it took to increase up to
the upper limit. When the output reaches the lower limit, the
calibrator retains the output as is for approximately three sec-
onds, and then automatically turns it off. Thus, one cycle of
sweeping is completed.
Step 9: To quit the sweep function, turn off the calibrator by pressing
the
key.
Step 10: Place switch 1 back in the OFF (left-side) position to disable
the sweep function.
NOTE
• When the output reaches the lower limit, the calibrator retains the output as
is for three seconds, and then turns it off. Thus, one cycle of sweeping is
completed.
• To alter the direction in which the output changes, press the
key when
sweeping is in progress (LCD reading is changing). The calibrator alters the
direction of change and continues sweep operation. For example, pressing
the
key during an increase in the output causes the output to begin
decreasing.
