This warranty does not cover accessories not of Associated Power Technologies, Inc. manufacture. Except as provided herein, APT, makes no warranties to the purchaser of this instrument and all other warranties, expressed or implied (including, without limitation, merchantability or fitness for a particular purpose) are hereby excluded, disclaimed and waived.
Page 8: Glossary Of Terms
warranty can be extended for a full year at the cost of an annual calibration. Glossary of Terms Alternating Current (AC) - current that reverses direction on a regular basis (usually 60 times per second in the United States). Measured in amps. AC Power Source - An instrument that takes one AC voltage and frequency level and converts it into another AC voltage and frequency level.
Page 9 OC Fold - Over current fold back is a technology used in power sources that keeps output current constant by reducing the voltage in order to power loads that may have a high inrush current. Parallel Mode - up to 3x 300XAC modular AC power sources can be configured with their outputs tied in parallel, allowing for the system to output three times a single instrument's nominal output current rating.
Page 10 SmartDetect - this feature automatically assigns the appropriate master/slave designation for each AC power source in a linked system without the need for the operator to reconfigure internal hardware. Steady State Current - A term used to describe the current when the load is running nominally after the inrush current.

(1) or two (2) additional model 310XAC instruments. A model 310XAC cannot be interconnected with a different model such as the 320XAC. 6.1.1 Operating Mode Definitions When multiple instruments are connected together, the operator has the option to run the instruments in Parallel or Polyphase modes.
Page 106: Output Wiring Diagrams
The operator does not need to adjust any settings on the instruments’ front panel. APT’s SmartConfig feature will automatically adjust the firmware to display the appropriate output modes depending on the number of sources that are interconnected.
Page 107 Polyphase Mode (1Φ3W) In this configuration, the operator must connect the Neutrals of both instruments together and utilize both Line outputs to achieve full voltage. See the figure below for the 1Φ3W output wiring diagram: Polyphase Mode (3Φ4W) In this configuration, the operator must connect the Neutrals of all sources together and utilize the Line outputs to achieve full voltage.

Page 153 Product A has barcode “123456789”, then the test file that the user would like to run when testing Product A should be named “123456789”. When the product’s barcode is scanned, the APT 300XAC will immediately execute the test associated with that barcode. The test file name is limited to 10 characters.
Page 154: Autostart
If the Barcode INPUT is set to PRODUCT#, scan the barcode once to input it into the APT 300XAC. The APT 300XAC will then search for a test file name that matches the product number barcode string. If the APT 300XAC finds a match, it will load the file into RAM.

PRODUCT#. The Autostart feature will not work with the SERIAL# setting. The Autostart feature will enable the instrument’s output once the product number barcode is scanned a second time when in the PRODUCT# and SER/PROD modes. Do not touch the DUT at any time when using this feature in order to avoid potential shock or serious injury.
