easy to use and will find many uses for testing DC power supplies,
batteries, and DC to DC converters.
Full digital control
1mV /1mA measurement resolution
Compact size
Bright, readable LED display
Operating modes: CC/CV/CR
Input on/off control
High reliability due to OCP/OVP (over
current, over voltage) protection
Storage for *40 groups, 4 setups
each
Easy operation
Features

LIST mode is an added feature applicable for newer firmware versions of 8540,
specifically version 1.60 or above. This feature allows users to program a list of
sequence steps that may be useful in some automated test applications or
Go/No Go type of testing. This feature can only be used when the load is
booted into this mode. It cannot be used in conjunction with normal operating
mode that allows you to quickly set your settings or do save/recall setup
operations. Users can choose to either run in normal operating mode or in list
mode. NOTE: Unlike normal operation mode, list mode operates in 30 A
range and is fixed.
How to access LIST function
To boot the instrument into LIST mode, first power OFF the instrument. Now,
press and hold the key while switching the power to ON. At this point, the
load will enter LIST function, and all other keys will not function like it would in
normal mode. They will instead, be used for setting up and controlling list mode.
LIST mode structure
The LIST mode feature allows users to program and store into internal memory
up to 4 sequences with maximum of 25 steps in each sequence. The storage
memory is broken down into 4 blocks for storing sequences. We will refer these
sequences as A, B, C, and D.
- SequenceA stores step 0 to 24 (25 steps total).
- Sequence B stores step 25 to 49 (25 steps total).
- Sequence C stores step 50 to 74 (25 steps total).
- Sequence D stores step 75 to 99 (25 steps total).
Users can store a combine (all 4 sequences) total of 100 steps, but are only
allowed to run one sequence (for maximum of 25 steps) at a time.
Programmable List Settings
When programming each step, users can program the following:
(Note: Words in bold is the parameter name and words in () is what’s shown on
the top display of the instrument when the parameter in bold is selected)
-Type (tyPE) - Refers CC/CV/CR modes)
-Data (dAt) – Refers to the actual step value. Units are in amps (A) for CC,
volts (V) for CV, and ohms (Ω) for CR mode.
-Delay Time (dt) – Refers to the step time, which is the time to hold the
programmed step value. Programmable range: 0.4 seconds to 25 seconds
-*HV (HU) – Refers to upper limit of the input voltage.
-*LV (LU) – Refers to the lower limit of the input voltage.
-*HA (HA) – Refers to the upper limit of the input current.
-*LA (LA) – Refers to the lower limit of the input current.
*Denotes parameters that can be used for Go/No Go or limits testing. Refer to
“Setup List Parameters” section below for details.

Setup List Parameters
Below is an example with step by step instructions on setting up a sequence
using list modes.
Step 1 – Select step number to
program
If not already, boot the instrument
into LIST mode by holding the
key while switching on the power
button. Press , then
to enter the LIST menu for
programming LIST parameters.
The display will look like the one
on the right.
If you want to program from the
first step, leave it shown on the
bottom display as 0. In this
example, we will start from 0. After
entering all parameters assigned
for the step, the menu system will
automatically go back to this setup
screen with step number
automatically incremented by 1.
You only need to adjust this if you
want to edit a programmed step
later on or if you want to program a
different step.

Run Programmed Sequence
After programming and saving the sequence(s), you can start running those
sequences by doing the following (Only 25 steps can be run at one time):
- Press key to run programmed steps 0 to 24.
- Press key to run programmed steps 25 to 49.
- Press key to run programmed steps 50 to 74.
- Press key to run programmed steps 75 to 99.
When sequence is running, a beep sound will occur whenever it jumps to the
next step.
Although programmed steps can be set with minimum resolution of 1 mA/1
mV/1 mΩ, when running the sequence the minimum display resolution will only
be 10 mA/10 mV/10 mΩ.
The running sequence will stop if the step data value is 0.000. It will not run all
25 steps in each sequence unless each step has a data value greater than
0.000.
CAUTION:
Once a sequence starts running, other key press will interrupt the setting, but
the sequence will still continue to run until it ends. Additionally, the input will
turn ON automatically. To stop the sequence immediately, go into the LIST
menu and exit again. This will stop the sequence, but input status will remain
ON if it was already ON prior to entering the LIST menu. Otherwise, turning the
power switch OFF will be the quickest and safest way to end the run.
