CHANGINGTESTMODES
5.
The 300XAC includes two test modes that change the way in which the AC power
source operates. PROGRAM Mode allows the operator to configure and run a test
using steps and memory locations within the AC power source’s menu. PROGRAM
Mode is designed for advanced testing applications. MANUAL Mode doesn’t
utilize steps and memories, allowing the operator to quickly run a test with basic test
parameters.
Turn the POWER switch to ON. From the Set screen press the “<more>” soft key and
press the “System” soft key in the next screen.
In the System Parameters Menu, you can use the up or down arrow soft keys to
highlight the AUTO RUN parameter. To change the AUTO RUN parameter, press the
“Edit” soft key.
In the next screen, the AUTO RUN parameter will be highlighted. Press the
“Change” soft key to toggle the highlighted parameter between PROGRAM and
MANUAL mode. Press the “Enter” soft key to save changes made and then press the
“Exit” soft key two times to return to the Set screen.
When the AUTO RUN parameter in the System Parameters menu is set to PROGRAM
mode, the Set screen will be displayed as follows: (See Figure 1)
(Figure 1. Set Screen)
When the AUTO RUN parameter in the System Parameters is set to the MANUAL
mode the Set screen will be displayed as follows: (See Figure 2)
(Figure 2. Set Screen)

USING THE 300XAC IN CONSTANT CURRENT MODE
1) Turn ON the OC FOLD parameter.
From the Set screen press the “<more>” soft key and press the “System” soft key in
the next screen.
In the System Parameters Menu, you can use the up or down arrow soft keys to
highlight the “OC FOLD” parameter. To change the “OC FOLD” parameter, press
the “Edit” soft key.
In the next screen, the “OC FOLD” parameter will be highlighted. Press the
“Change” soft key to set the highlighted parameter to ON. Press the “Enter” soft key
to save changes. Press the “Exit” soft key two times to return to the Set screen.
2) Program a current Hi-Limit, which represents the constant current you will
provide to the load.
From the Set screen press the “Edit” soft key.
In the next screen, the Edit Parameters Menu, you can use the up and down
arrow soft keys to highlight the “A Hi-Lmt” parameter. To change the “A Hi-Lmt”
parameter, press the “Edit” soft key.
In the next screen, the “A Hi-Lmt” parameter will be highlighted. Using the Numeric
Keypad enter the desired current limit. Press the “Enter” soft key to save changes
and then press the “Exit” soft key one time to return to the Edit Parameters Menu.
3) Program the voltage.
From the Edit Parameters Menu, use the up or down arrow soft keys to highlight the
“Voltage” parameter. To change the “Voltage” parameter, press the “Edit” soft key.
In the next screen, the “Voltage” parameter will be highlighted. Using the numeric
keypad, enter the voltage value. The voltage should be set higher than the nominal
load voltage. This allows the current to adjust to the Hi-Limit value. After you enter
the voltage, press the “Enter” soft key and then press the “Exit” soft key two times to
return to the Set screen.

PARALLEL MODE (1Ø2W)
In Parallel Mode, two (2) or three (3) instruments may be connected together in
parallel, to increase the total current output of the system.
Linking two 300XAC sources:
Only one linking cable is needed. Connect the linking cable from the output
connector labeled “Link Output” of one 300XAC source’s linking card to the input
connector labeled “Link Input” of the second 300XAC source’s linking card.
(See Figure 3)
Linking three 300XAC sources:
Take a second linking cable and connect it from the second 300XAC source’s output
connector labeled “Link Output” on the linking card to the input connector labeled
“Link Input on the third 300XAC source’s linking card. (See Figure 3)
(Figure 3.)
LINKINGSOURCES
IMPORTANT: BEFORE YOU BEGIN MAKING CONNECTIONS, YOU MUST
ENSURE THAT THE POWER SWITCH ON THE 300XAC INSTRUMENT IS IN THE

In Parallel Mode, each instruments’ LINE output must be connected together at the
load. If you are linking two sources there will be two line connections. If you are
linking three sources there will be three line connections. (See Figure 4)
Also, each instruments’ NEUTRAL output must be connected together at a load. If
you are linking two sources there will be two neutral connections. If you are linking
three sources there will be three neutral connections. (See Figure 4)
(Figure 4)
Once all the linking cables and conductor connections have been made, you can
power up each individual 300XAC via the Power Switch on the front panel. Upon
power up, the 300XAC will go through an initialization screen to verify that the
additional sources are interconnected via the linking cable. If there is a proper
connection, a message will appear acknowledging that additional 300XAC sources
are linked and prompting the user to enable the additional sources.

The FUNCTION mode changes the output voltage configuration.
Power up all instruments. From the Set screen press the “<more>” soft key and in the
next screen press the “System” soft key.
In the System Parameters Menu, you can use the up or down arrow soft keys to
highlight the FUNCTION parameter.
When the FUNCTION parameter is highlighted, press the “Edit” soft key and use the
“Change” soft key to select the FUNCTION mode to “PARALLEL”.
To save changes made, press the “Enter” soft key and then press the “Exit” soft key

POLYPHASE OUTPUT MODE (1Ø3W)
In Polyphase Mode, two (2) or three (3) instruments connected together may be used to
increase the total voltage output of the system, or change the output configuration from
1Ø to 3Ø. If two (2) instruments are interconnected 1Ø3W mode is available. This
mode allows the operator to increase the output voltage to up to 600 VAC by configuring
the two sources to output voltage at 180 degrees apart
You will only use one linking cable between the two 300XAC sources. Connect the
linking cable from the output connector labeled “Link Output” of one 300XAC source’s
linking card to the input connector labeled “Link Input” of the second 300XAC source’s
linking card. (See Figure 5)
In the configuration below, the operator must connect the NEUTRALS of both instruments
together and utilize both LINE outputs to achieve full voltage. (See Figure 5)

POLYPHASE OUTPUT MODE (3Ø4W)
If three (3) instruments are interconnected 3Ø4W mode is available. This mode allows
the operator to configure the instruments for three phase operation. Each phase will
output voltage 120 degrees apart.
You will be using two linking cables between the three 300XAC sources. Connect
the linking cable from the output connector labeled “Link Ouput” of one 300XAC
source’s linking card to the input connector labeled “Link Input” of the second 300XAC
source’s linking card.
Now, take a second linking cable and connect it from the second 300XAC source’s
output connector labeled “Link Output” on the linking card to the input connector labeled
“Link Input” on the third 300XAC source’s linking card. (See Figure 6)
In the configuration below, the operator must connect the NEUTRALS of all sources
