5322A-LOAD
High Voltage Load Adapter
Instructions
Introduction
The 5322A-LOAD High Voltage Load Adapter (the
Product) loads a hipot tester to create leakage current
during hipot tester calibration with the 5322A
Multifunction Electrical Tester Calibrator (hereafter the
Calibrator). As shown in Figure 1, the Product consists
of nine power-rated resistors configured to provide
nine resistance taps from 10 kΩto 10 MΩ. Each of the
nine resistors in the Product can be put in parallel with
any other resistor. To do this, use the supplied high-
voltage jumper leads to short the resistor's red terminal
to the resistor’s corresponding black terminal.The
Product withstands a maximum voltage of 1.2 kV to
5.5 kV, depending upon the selected resistor.

This product complies with the WEEE
Directive marking requirements. The affixed
label indicates that you must not discard this
electrical/electronic product in domestic
household waste. Product Category: With
reference to the equipment types in the
WEEE Directive Annex I, this product is
classed as category 9 "Monitoring and
Control Instrumentation" product. Do not
dispose of this product as unsorted
municipal waste.
Preparing for Operation
The Product (see Figure 2) comes with a power line
adapter (to run the cooling fans), a ground cable, three
shorting cables, and these instructions.
The power line adapter comes with five mains plug
adapters that are compatible with different power plug
configurations.
Prior to use:
1. Select the appropriate plug adapter that matches
the local power mains outlet.
2. Attach the plug to the power line adapter. The
power line adapter is now ready for use with the
Product.
3. Once you place the Product on top of the
Calibrator, connect the grounding cable between
the Product’s rear-panel ground terminal and the
rear-panel ground terminal of the Calibrator. See
the grounding cable connection in Figure 3 where
the rear of the Product is shown.
XW Warning
To prevent possible electrical shock, fire,
or personal injury:
•Make sure that the ground terminal on
the rear of the Product is connected to
the ground (GND) terminal on the rear
of the Calibrator. Any application with
non-grounded housing is strictly
prohibited.
•Use only the shrouded high-voltage
banana plug jumpers that are supplied
with this Product to connect resistor
values. Connect the black terminal first
and disconnect the black terminal last
when you connect resistors.

WCaution
To prevent damage to the Product, make
sure that the vents on the bottom of the
Product and the fan exhaust vents are
clear of obstructions for proper cooling.
Connect one end of the power line adapter to the
mating power input connector socket on the rear panel
of the Product and the other end to the mains power
outlet.
WCaution
Failure to have the fans operating may
lead to over heating and component
failure.
Push the rear-panel switch to the “I” side of the switch
to turn on the cooling fans. A light on the front panel
illuminates and indicates that power is on. Turn off the
power switch when the Product is no longer being
used.

Use the Load for Leakage Current
Tests
Select the load resistor based on the appropriate
voltage amplitude for the test or the value
recommended in the hipot tester’s calibration
procedure. A load resistor is connected to the Output
terminals when a resistor's red and black terminals
are shorted together using a high-voltage shrouded
banana jumper lead.
See Paralleling Resistors for making additional
resistance values. See the 5322A Operators Manual
for more detailed application information.
WCaution
To avoid damage, never exceed the
maximum rated voltage, power, and
current limit of the Product.
Usage Limits for Safe Operation for Each
Load Resistor
Safe operation of the Product depends on the amount
of voltage and the length of time it is applied to the
Product. For the 10 kΩ, 35 kΩ, 50 kΩ, 100 kΩ, and
250 kΩresistors, there are time limits where the
higher-voltage levels can be safely applied. This is
graphically shown in Figure 4 for the 10k, 25k, 50k,
100k, and 250k resistors.The maximum voltages can
be applied for up to 3 minutes for these resistors. Due
to self heating, exceeding the 3-minute limit for high
voltages can cause both degradation of performance
and a permanent shift in the resistor value. However,
reduced-voltage levels can be safely applied for
increasing longer times. At specific levels, sustained
voltages can be applied indefinitely. The other
resistors (500k, 1M, 5M and 10M) do not have a time
limit for the maximum voltage (5500V). See Figure 4.

The 100 kΩresistor can withstand 5500 V for
3 minutes while it can withstand 4000 V for
60 minutes or longer.
Paralleling Resistors
The Product can output additional values by placing
combinations of the nine resistors in parallel as shown
in Table 2.
To place resistors in parallel, short together
combinations of the given resistors’ red and black
terminals using the supplied high-voltage shrouded
banana jumper leads. For example, to parallel the
10 kΩand 25 kΩresistors, short the 10 kΩred and
black terminals, and the 25 kΩred and black
terminals. This places these two resistors in parallel at
the Product Output terminals. The resultant output is
7.14 kΩ, for a 70 mA leakage current at 500 V, as
shown in Table 2.
In Figure 5, the 10k Ohm, 25k Ohm, and 50k Ohm
resistors are in parallel, giving an output of 6.25 kΩ.

To set up a leakage current of 3 mA at a test voltage
of 1000 V, find the row in Table 2 for 3 mA and then
select the desired test voltage. For 1000 V, parallel
the 500 kΩand 1 MΩresistors to make a 333.33 kΩ
output.

Performance and Verification Test
With normal operation, verify the resistance values of
the Product at least once per year. Also, verify the
load resistor if there is a possibility of the resistance
values changing due to excessive heating or power
dissipation.
To verify the electrical performance of the Product,
use one of these test methods to ensure the load
resistors are within specification:
•Voltage Test Method - Use voltage and current
levels that ensure that the resistors dissipate a
reasonable power as they are verified.
•Mutlimeter Test Method - Use a multimeter to
measure the load resistance.
Both methods check to see if it is within 10 % of the
nominal value. The multimeter test uses minimal
voltage and current levels, dissipating negligible
power when measuring the resistance values of the
load resistance.
Either test method can be used, but Fluke Calibration
recommends the voltage method as it verifies the
resistance value while the resistor disipates actual
power – similar to the normal usage of the Product.
The voltage method signal levels are based on
capabilities of the recommended voltage calibrators.
These levels use voltages up to 1 kV. It is possible
and acceptable to test using other sources to test at
higher voltages, but staying within the limits of the
Product’s safe area of operation.
Table 3 lists the load resistance nominal value for
each load resistor terminal.
To use the voltage test method, apply a test voltage
across each resistance, between the respective input
and COM terminals. The resulting current through the
resistor is measured, and the value of the resistance
is calculated. Use a calibrator as the precision-voltage
source. Use a multimeter to measure the current.
Figure 6 shows the test equipment setup. Refer to
Table 3 for the respective sourced voltage level
settings and the nominal currents to be measured.
Note
Fluke Calibration recommends a Fluke
5520A or 5500A Calibrator as a source
for the voltage method due to its output
voltage/current capabilities. Fluke
Calibration recommends a Fluke
8845A Digital Multimeter (or
equivalent) for measurements with
either test method.
For the voltage test method, test each resistor as
follows:
1. Apply the recommended voltage (Vs) at power
mains frequency (either 50 Hz or 60 Hz) between
the terminal for the resistor being measured and
the COM terminal.
2. Measure the current (Im) flowing through the load.
3. Calculate the resistance (RL) by dividing the
sourced voltage by the measured current
(RL=Vs/Im).
The calculated resistance should be within 10 % of
the nominal resistance value found in Table 3.
Repeat steps 1 through 3 for each load resistor
terminal and adjust the applied voltage per Table 3.
For the alternative multimeter test method, measure
each resistor as follows:
1. Place the probes of a multimeter between the
selected resistor input (red) terminal and the COM
terminal.
2. Read the measured resistor using the resistance
mode of the multimeter, and note the value.
3. Ensure the measured value is within 10 % of the
nominal resistance.
Repeat steps 1 through 3 for each load resistor
terminal per Table 3.
