On page 7-8, replace the first Note with the following:
Note
The Resistance Multiplier is only used with insulation resistance testers with a third
terminal, commonly called the Guard terminal. Most testers of this type use a virtual
ground sensing circuit, that causes an input resistance of 0
 . The Calibrator can
accommodate testers that have either 0
 input impedance or a finite input impedance.
The Calibrator has a setup parameter, "R multiplier input", to accommodate different
input impedances for insulation testers. The "R multiplier input" has a default setting of
0
 for the most common type of testers with a virtual ground sensing circuit. For other
testers with an infinite input impedance, the "R multiplier input" value must be set to
match the input resistance of the Unit Under Test.
To access the "R multiplier input" setting, press , press the softkey labeled Setup,
scroll down to High Resistance Source and then press the softkey labeled Select.
Choose "R multiplier input", which can be changed from 0 to 100.00 M
 .

Calibrator (5320A). 115 V or 230 V for example. Set the multifunction calibrator frequency to
55 Hz.

On page 6-4, prior to Cleaning the Air Filter, add:
Cleaning the Ground Bond Resistance and Loop/Line Impedance Relays
The power relays used in the Ground Bond Resistance and Loop/Line Impedance functions require periodic
cleaning to minimize their contact resistance. Relay cleaning should be performed once per month if the
Ground Bond Resistance or Loop/Line Impedance functions are used daily. If these functions are used less
often, relay cleaning should be performed every 90 days. If the 5320A has been powered off for more than 30
days, the relay cleaning procedure should be performed before usage.
The 5320A, with serial numbers higher than xx548xxxx, is equipped with an internal power source that
provides current during the cleaning procedure. For 5320As with serial numbers lower than 548xxxxxx, an
external power supply must be connected to the PE and N terminals. See the next section for details.
Relay cleaning is started manually from the SETUP menu, and exercises the relays on the REL board a number
of times with current flowing through them. To perform the relay cleaning procedure, disconnect all external
connections to the 5320A front panel.
Select Maintenance
Then select Relays cleaning procedure

Select Start. When the procedure is running, the following information is displayed:
The procedure lasts about 30 seconds. During the procedure, the 5320A cannot be operated. When the cleaning
procedure is complete, push the soft key Exit a number of times to return to the main menu.
Cleaning the Relays for Serial Numbers Lower than xx548xxxx.
5320As with serial number lower than xx548xxxx do not have an internal power supply for relay cleaning, and
must be connected to an external power supply for this procedure. This power supply must provide, at least
20 V with 3 A of current.
To clean the relays:
1. Remove all external connections to the 5320A front panel.
2. Navigate to the Relay cleaning procedure as outlined above. Do not start the procedure.
3. Set the external power supply to 20 V and connect as shown to the PE and N terminals of the 5320A. It
is best to use an external analog (linear) supply source. If a switching dc supply source is used, two
resistors and one capacitor should be inserted between the power supply output and the 5320A input as
shown in the diagram. Analog (linear) power supplies do not require this external resistor and capacitor
network.
4. Start the Relay cleaning procedure.
5. Remove the external power supply connections when complete.
6. Push the Exit soft key a number of times to return to the main menu.

Note
For units with serial number lower than xx548xxxx, do not run the cleaning procedure
without connecting the external power supply. When the cleaning procedure is performed
without connecting the external power supply, the relay contact resistance may become
even worse. Changing the polarity of the dc supply source is recommended from cleaning
to cleaning to avoid one-way transport of contact material from one side of the contacts
to the other.

On page 1-7, add the following to the Symbols table:
ÃConforms to relevant South Korean EMC
Standards.
On page 1-9, add the following to the General Specifications:
Electromagnetic Compatibility (EMC)
International......................................IEC 61326-1: Basic Electromagnetic Environment
CISPR 11: Group 1, Class A
Group 1: Equipment has intentionally generated and/or uses conductively-coupled
radio frequency energy that is necessary for the internal function of the equipment
itself.
Class A: Equipment is suitable for use in all establishments other than domestic and
those directly connected to a low-voltage power supply network that supplies
buildings used for domestic purposes. There may be potential difficulties in ensuring
electromagnetic compatibility in other environments due to conducted and radiated
disturbances.
Emissions that exceed the levels required by CISPR 11 can occur when the
equipment is connected to a test object.
Korea (KCC).....................................Class A Equipment (Industrial Broadcasting & Communication Equipment)
Class A: Equipment meets requirements for industrial electromagnetic wave
equipment and the seller or user should take notice of it. This equipment is intended
for use in business environments and not to be used in homes.
USA (FCC) .......................................47 CFR 15 subpart B. This product is considered an exempt device per clause 15.103.

On page 1-9, under WFuse Protection, replace the existing content with:
RCD input.........................................3.15 A, 250 V, Fast (F3.15H250V – 5 mm x 20 mm)
Meter amps (A) input........................20 A, 500 V, Fast (T20H500 V – 6.3 mm x 32 mm)
Loop/Line impedance input...............4 A, 500 V, Time delay (T4H500 V – 6.3 mm x 32 mm)
On page 4-6, following Table 4-2, replace the sentence with:
An optional resistance multiplier is offered to increase the range of high resistances from 350 MΩto
10 TΩand applicable dc test voltage to 5 KV. Resistance multiplier is based on a passive T-type
resistance network. Nominal value of multiplication is 1000. Exact value depends on resistance
multiplier calibration data. Input resistance of the multiplier is approximately-300 MΩ. Resistance
multiplier can be applied for calibration of such UUTs which use virtual ground (current to voltage
converter) as current sense terminal with input resistance. For UUTs with finite input resistance and
non-virtual ground on sense terminal, the input resistance must be taken into consideration. For this
purpose, the Calibrator is equipped with a parameter “R multiplier input”. Input resistance of sense
terminal of UUT should be written here to perform calibration correctly.
Note
Input resistance of the sense terminal is different for different models of megohmmeter.
Do not to set the parameter to the correct value. For megohmmeters with virtual ground,
0 Ωmust be written and saved here before calibration.
