3.2.5. Left 5 digit LCD display
The 5 digit LCD display is a multi-function display. The function of the display
Changes depending whether the user is in NORMAL mode or in a SHORT, OPP or
OCP test modes:
Normal mode:
The left 5 digit display displays the voltage present at the load’s input terminals.
The value displayed will include the automatic voltage compensation if the sense
Terminals are also connected to the device under test (DUT)
Please note that if V-sense is set to ‘AUTO’ and the sense leads are connected to
The DUT the losses need to be approx. 700mV (3350F) before the display
compensates for the voltage loss.
If V-sense is set to ‘ON’ and the sense terminals are connected to the DUT the
Load will check and compensate for all voltage drops.
Test Mode:
If the SHORT, OPP or OCP buttons are pressed the upper display will show a text
Message that correlates with the selected test function.
SHORT test selected: left display will show “Short”.
OPP test selected:left display will show “OPP”.
OCP test selected: left display will show “OCP”.
During the test the left display will show the load Input voltage.
3.2.6. Middle 5 digit LCD display
The middle 5 digit displays also changes function depending if the user is in
Normal mode or has entered a setting menu
Normal mode:
In normal mode the middle LCD display functions as a 5 digit ammeter. The 5 digit
DAM shows the load current flowing into the DC load when the Load is ON.
Setting Mode:
If CONFIG, LIMIT, DYN, SHORT, OPP or OCP buttons are pressed the middle
LCD shows a text message according to the setting function it is in. Each
Subsequent press of the button moves the display to the next available function.
The sequence of each setting menu is detailed below
•
