A measure of the contaminants that could occur in the environment around and within a product. Typically the internal environment inside a product is considered to be the same as the external. Products should be used only in the environment for which they are rated.
Pollution degree 1. No pollution or only d ry, nonconductive pollution occurs. Products in this category are generally encapsulated, hermetically se aled, or located in clean rooms.
Pollution degree 2. Normally only dry, nonconductive pollution occurs. Occasionally a temporary conductivity that is caused by condensation must be expected. This location is a typical ofce/home environment. Temporary condensation occurs only when the product is out of service.
Pollution degree 3. Conductive pollution, or dry, nonconductive pollution that becomes conductive due to condensation. These are sheltered locations where neither temperature nor humidity is controlled. The area is protected from direct sunshine, rain, or direct wind.
Pollution degree 4. Pollution that generates persistent conductivity through conductive dust, rain, or snow. Typical outdoor locations.

ed
Before you begin - safety
Carefully r the Power Analyzer.
WARNING. To avoid possible electric shock or personal injury:
• By connecting the Power Analyzer to active circuits, the terminals and certain parts inside the Power Analyzer are live.
• If possible, open the circuit before establishing a connection to the Power Analyzer.
• Before connecting the circuits, ensure that the maximum measuring voltage and maximum
• Do not use leads and accessories that do not comply with relevant safety standards, as this could lead to serious injury or death from electric shock.
• Shunts and conductors can generate heat when in use and surfaces may burn the skin.

To connect an external resistive shunt
Using a resistive shunt is a straightforward method of extending the current measuring range of the PA1000. The shunt resistor is connected in series with the load and the voltage across the shunt is directly proportional to current.
That voltage may be connected directly to the External Current Inputs of the PA1000.

For example, a 1 milliohm shunt is used to measure 200 A
RMS

1. Check that the voltage that will be generated is suitable for the PA1000

Commands and re
sponses are sent as ASCII strings terminated with a line feed. The PA1000 is not case sensitive and white space characters are ignored except where required between command and parameter.
Multiple commands cannot be sent in a single string where a ‘;’ character is used at the end of each command.
For all commands where a parameter i s s upplied, one or more spaces are required between the end of the command and the rst paramete r. For example, “:CAL:DATE 1” will work. “:CAL:DATE?1” will cause a time out error.
All non-common commands (those with ‘*’ as the rst character) must have a leading colon ‘:’. Although the IEEE 488.2 standard does not require this, the PA1000 does. For example, :avg? works, but Avg? does not. :avg:aut works but avg:aut does not.
The list of commands is split into relevant sections. In general each section corresponds to a menu option from the main menu on the PA1000.

Sending and re

As stated before, there are many ways in which to send commands to the PA1000, but there are some common rules for all methods:
All instructions should be terminated with a line feed (ASCII 10) character.
All returned information will be terminated by a line feed (ASCII 10)
character.
Only one instruction can be sent at a time. ":SEL:VLT;:SEL:AMP" is not a
valid command.
For all commands that congure the unit, allow 0.5 seconds between each
command or use ow control to wait until the next command is sent.
The running of auto-zero, which happens e very 1 minute, will result in no new
results for approximately 1 second. For this reason auto-zero can be disabled.
NOTE. When utilizing communications via the Ethernet interface on the PA1000,
all com i.e. ASCII CR (0x0D). In the examples below the carriage return character is represented by “[CR]”.

Tip. If using Visual Studio or Lab-View you can utilize the ‘Flush, In-buffer’ command to quickly and simply remove the carriage return from the input buffer. This can be set up as a discipline in the software to occur after every read and write command sent.
ample 1. User sends a query to the PA1000 to determine the status of the shunt.
Ex
The PA1000 will respond with a CR a dded to the end of the string;
ER: “:SHU?”
US
PA1000: “0[CR]”
The PA1000 responds as normal with a CR character added to the end of the string.
Example 2. User sends a command to the PA1000 to disable blanking and the PA1000 responds with a CR character;
USER: “:SHU:INT”

Introduc
tion
Power s upplies, adapters and common electrical and electronic goods often operate in standby mode. Examples are a TV switched ‘off’ by remote control but consuming power waiting for further remote control, a microwave oven just
ying its clock, or a cell phone charger that has nished charging. The
displa cumulative power drawn by these and other common loads is signicant and programs such as ENERGY STAR™ and the European Eco-Directives seek to limit the power drawn b y equipment when in this mode. Typical standby power levels continue to decrease from the 1 Watt initiative of 2010 towards the voluntary 30 mW of the European Community’s 5-star charger rating in 2014.
The standby power and the measured current are low compared to the normal operating point of the equipment under test. The power analyzer must measure perhaps below 100 uA yet also measure amps of full-load current. The analyzer

mu to measure the standby current and power accurately.

T supply in a burst mode. The power supply draws bursts of power from the ac line and then shuts down it internal circuits until more power is required. In this way, the power is drawn from the ac line in irregular bursts and to make an accurate measurement it is required to:

To take a standby power measurement using the PA1000 Standby Mode:
1. Connect the equipment under test using a Tektronix breakout box. Be careful to use the Vlo Source connection for voltage. This eliminates any errors due to the small current that ows between the voltage terminals of the PA1000.

Using a xed range while measuring w ill ensure that no data is lost during the ranging process. To set a xed range, choose Inputs > Fixed/Auto ranging > and choose a suitable xed range, based on the measurements made during auto-ranging. If the range is too low, a warning message will display.

IEC 61000-3-2 pre-compliance current harmonics testing
Introduction
The advent of new control techniques in power electronics, developed for higher efciency and compact designs, has led to poor power line quality. The problem keeps getting worse with higher switching speeds common to modern electronics and appliances and leads to increase in higher power line current harmonics. High current harmonics on the AC power line have many adverse effects like undesired overheating, stress on other equipment on the same line and product failure. H igher current harmonics can also lead to undesired high current in neutral conductor leading to overheating and burnout.
IEC (International Electrotechnical Commission) has recognized the ill-effects of excessive current harmonics and presented standards to limit them. Many national and regional authorities like European Union have harmonized the IEC standards to t with their respective regions.

The table below lists the formulae for calculating the accuracy specication for each measurement.
In the equations below:
It is assumed the waveform measured is a sine wave.
F is the frequency measured in kHz.
Fh is the harmonic frequency in kHz.
hn is the harmonic number
V is the voltage measured in Volts.
I is the current measured in Amps.
Θ is the phase angle in degrees (i.e. phase of the current with reference to
the voltage).
