AC/DC Output Voltage Duty Cycle
30 Minutes on followed by 30 minutes off.
Metering
Measured quantities such as AC Amperes, AC Volts, DC Volts or DC Amperes, and
Time, are all simultaneously displayed on the large variable contrast LCD screen.
The read-and-hold feature of the metering provides fast and accurate preset of test
values. The AC Amperes also displays a percent value when rotating the control
knob for easy reference by the user. The AC and DC Volts display the expected
voltage output prior to initiation of the voltage outputs. This provides a fast and easy
method for preset of voltage outputs. As a safety feature, it also alerts the user to
the expected voltage output prior to turning the voltage outputs on. Other values,
which may be displayed depending on which test screen is in view, are Phase
Angle, Power, Reactive Power and Power Factor. The large characters and
variable contrast make the display easy to read from 3 to 4 feet (1 meter) away,
even in direct sunlight. All accuracy stated below are for 10 to 100 % of Full Scale
at 50/60 Hz.
