5320A
Getting Started Manual
2
Insulation Resistance
For insulation resistance calibration, the Calibrator acts as a high resistance source from
10 kΩto 10 GΩwith 4½ digit resolution. A single value 100 GΩselection is available
as well. Depending on the selected resistance value, maximum applied test voltages
range from 50 to 1500 volts peak.
Earth Resistance and Continuity
The Calibrator sources low resistance values from 100 mΩto 10 kΩwith 3½ digits of
resolution. This function is used in either 2-wire or 4-wire mode to calibrate continuity
testers and earth resistance testers that source currents from 5 to 400 mA.
Loop, Line and Ground Bond Resistance
The Calibrator sources high power rated low resistance standards from 25 mΩto
1.8 kΩ, which are especially suited for loop impedance, line impedance, and ground
bond resistance testing. The Calibrator senses and displays Unit Under Test (UUT) test
conditions, types of test current, and current levels up to 25 amps. In the 5320A/VLC, an
Active Loop Compensation module will compensate for residual resistance when
performing loop and line impedance calibrations.
Residual Current Device Testing
In the RCD function, the Calibrator acts as a circuit breaker to calibrate trip time in the
range of 10 ms to 5 s and trip current in the range of 3 mA to 3 A. All tested parameters
of the UUT are scanned and displayed through the Calibrator’s front-panel display.
Leakage Current Source
The Calibrator sources simulated leakage current from 0 to 30 mA with a maximum
compliance voltage up to 250 V ac. Leakage current modes include touch, substitute and
differential current.
AC/DC Voltage Generation (5320A/VLC Only)
When equipped with the ac/dc voltage calibrator, the Calibrator is capable of calibrating
the voltmeter function on many electrical safety testers. The voltage range is 3 to 600
volts both ac and dc. The ac frequency range is 40 to 400 Hz. This voltage source also
generates stable power line voltage for powering appliance testers.
Meter Functions
The Calibrator is equipped with a built-in low frequency voltmeter and ammeter. The
voltmeter measures up to 1100 volts, while the ammeter measures up to 30 amps. UUT
power consumption is calculated by taking the measured voltage and current and then
calculating the VA.
Other Features
For ease of use, the Calibrator includes other features such as setup menus, a
recalibration procedure, correct power line connection testing, hardware and software
overload protection, and many others.
Front-panel control of the Calibrator is accomplished through function keys for
frequently used functions, edit controls and menu selection soft keys. All necessary
information such as Calibrator status, menu selections and readings are displayed
through a flat luminescent display on the front panel.
The Calibrator is equipped with an IEEE-488 bus, an RS-232 serial port and a LAN
interface, for controlling the Calibrator from a PC or instrument controller.
