measurement mode will often reset the voltage and current range to auto.

Scaling can be used to adjust the PA1000 values to account for the transducer ratio. The scaling factor will affect every measured value related to the input to which it is applied.

When the 600 V and 20 A and 1 A inputs are used directly, then the default setting for Volts and Amps scaling is 1.

To use the PA1000 with external voltage or current transducers, enter a scale factor to make the PA1000 display measurements with proper scaling, accounting for the transducer ratio.

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.

Connecting signals

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

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

V=IxR(Ohm’slaw)

Vshunt = I x Rshunt

Vshunt = 200 x 0.001 Ohms

Vshunt = 0.2 V

This is well within the 1 V rating of the External Current Inputs on the PA1000.

To connect a voltage transformer / transducer

The PA1000 may be used with a voltage transformer (VT) or other transducer to extend its measuring range. Follow the manufacturer’s instructions for the safe use and installation of the transducer.

The output of the transducer is connected to the normal VHI and VLO terminals. Normally, the positive or HI output of the transducer will be marked with the point of an arrow or a + symbol. Connect this terminal to the VHI input of the PA1000.

Voltage scaling

A voltage transformer (VT) produces a voltage output, which is proportional to the voltage being measured.

To measure the correct voltage on the PA1000, use the scale function of the analyzer to scale, or multiply, the VT output current.

Command listi

The following conventions are used in the next section to describe the command syntax:

Square brackets indicate optional parameters or keywords [ ]

Triangle brackets indicate values to be speciﬁed < >

Vertical bar indicates the choice of parameters |

Commands and responses 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 is supplied, one or more spaces are required between the end of the command and the ﬁrst parameter. For example, “:CAL:DATE 1” will work. “:CAL:DATE?1” will cause a time out error.

All non-common commands (those with ‘*’ as the ﬁrst 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

aut does not.

avg:

The list of commands is split into relevant sections. In general each section

responds to a menu option from the main menu on the PA1000.

Sending and re

ceiving commands

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 conﬁgure the unit, allow 0.5 seconds between each

command or use ﬂow control to wait until the next command is sent.

The running of auto-zero, which happens every 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]”.

munications will be responded to with a carriage return character,

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.

The PA1000 will respond with a CR added to the end of the string;

ER: “:SHU?”

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”

PA1000: “[CR]”

The PA1000 responds with a CR character.

Utilizing all other communication methods the PA1000 does not reply with a CR to every communication.
