Safety Symbols
WARNING
to the manual (see the Index for references).
Risk of electric shock. Refer
GROUND Ground terminal to chassis
(earth).
Attention Refer to the manual (see the
Index for references). This symbol indicates that information about usage of a feature is contained in the manual. This symbol appears on the rear panel ground terminal and by the fuse compartment.
AC Power Source
The instrument is intended to operate from an ac power source that will not apply more than 264V ac rms between the supply conductors or between either supply conductor and ground.
Use the Proper Fuse
For fuse replacement use: 110 or 120 V operation,
2.5 ampere/250 volt time delay; 220 or 240 V operation, 1.25 ampere/250 volt time delay.
Grounding the instrument
The enclosure must be grounded through the grounding conductor of the power cord, or through the rear panel ground binding post.
Use the Proper Power Cord
Use only the power cord and connector appropriate for the voltage and plug configuration in your country. Use only a power cord that is in good condition. Refer power cord and connector changes to qualified service personnel.
CAUTION
Verify applied voltage to the UUT does not exceed the UUT insulation rating.
Replacing the Fuse
Disconnect line power. Follow the figure below for fuse replacement.

WARNING
To avoid shock hazard, connect the factory supplied three­conductor line power cord to a properly grounded power outlet. Do not use a two-conductor adapter or extension cord; this will break the protective ground connection.
Use the rear-panel ground terminal for a protective grounding wire if there is any question as to instrument earth grounding.
CHASSIS GROUND Binding post is internally
grounded to the chassis.
8 AC Power Input Module Provides a
grounded three-prong connector that accepts the line power cord, a switch mechanism to select the operating line voltage, and a line power fuse.

Zeroing the Calibrator
To meet the specifications, zeroing is required every 7 days, or when the 5500A Calibrator ambient temperature changes by more than 5 °C. Choose from complete instrument zeroing (ZERO) or ohms-only zeroing (OHMS ZERO).
1. Turn on Calibrator and warmup (30 minutes).
2. Press R key.
3. Install copper short circuit in TC connector (complete instrument zeroing only).
4. Press S key, opening setup menu.

Operate and Standby
To enable the operate mode, press O. To place the calibrator in standby, press Y.
The calibrator goes into the standby if:
The R key is pressed.
A voltage ≥33V is selected when the previous
output voltage was less than 33V.
Function changed.
Output location is changed.
Overload condition is detected.
Connecting the Calibrator to a UUT
WARNING
The 5500A Calibrator is capable of supplying lethal voltages. Do not make connections to the output terminals when a voltage is present. Placing the instrument in standby may not be enough to avoid shock hazard, since the O key could be pressed accidentally. Press reset and verify that the Y annunciator is lit before making connections to the output terminals.
When to Use EARTH
The Z key makes a connection between the NORMAL LO terminal and earth ground. When the common ground is not at the UUT, use Z to make a common ground at the calibrator.
Four-Wire versus Two-Wire Connections
The external sensing capability of the four- and two-wire compensated connections provides increased precision for resistance values below 110 k and capacitance values 110 nf and above.

Using the 5725A Amplifier
In voltage boost mode, 5725A output appears on 5500A NORMAL terminals. In current boost mode, 5725A output appears on 5725A terminals. Redirected 5500A current to 5725A output terminals is 0 - 2.2 A dc, and 300 µA - 2.2 A ac.
Rules of Operation
Whenever B key annunciator is on, 5725A voltage boost or current boost amplifier is in use.
If 5725A Current Amplifier indicator is on, while B annunciator is off, 5500A current is being redirected to 5725A.
When sourcing current, OUTPUT softkey choice AUX or BOOST takes precedence over Source Preference softkey and front panel B key. Exception: When selected current cannot be sourced by 5500A, output automatically switches to BOOST and displays Current OUTPUT moved to 5725A in Control Display.
Source Preference softkey chooses 5500A or 5725A when either can source output. B key is a temporary Source Preference selection.
Any current or voltage combination outside capabilities of 5500A but within capabilities of 5725A will activate 5725A output.

5725A Amplifier Output
WARNING
Boosted voltage operation produces high voltage at higher current levels than normally available from the calibrator. During boosted voltage operation, the potential risk of injury or fatal accident is greater than during normal operation.
Set a boosted output from 5725A Amplifier:
1. Press R to clear 5500A output.
2. Install 5725A, as described in 5725A manual.
3. Connect UUT. For boosted current, connect to 5725A terminals; for boosted voltage, connect to 5500A NORMAL terminals.
4. Set UUT to measure output.
5. Set source preference to 5725: press front panel S key; softkey INSTMT SETUP; softkey OUTPUT SETUP; softkey SOURCE PREFRNCE to select 5725.
6. Press P key one or more times to return to previous menus.
7. Enter desired output value described under
“Setting the Output.”
NOTE
You can have the 5725A source a dc current
below 1.5 A to take advantage of the
amplifier’s higher compliance voltage. To do so, press the RANGE softkey to lock onto the 11 A range when the 5500A is set for over 2.2 A, or set the lower current and press
