SAFETY INSTRUCTIONS
This chapter contains important safety
instructions that you must follow during
operation and storage. Read the following before
any operation to insure your safety and to keep
the instrument in the best possible condition.
Safety Symbols
These safety symbols may appear in this manual or on the
instrument.

SAFETY INSTRUCTIONS
Do not dispose electronic equipment as unsorted
municipal waste. Please use a separate collection
facility or contact the supplier from which this
instrument was purchased.
General
Guideline
CAUTION
Do not place any heavy object on the 2260B.
Avoid severe impact or rough handling that
leads to damaging the 2260B.
Do not discharge static electricity to the 2260B.
Use only mating connectors, not bare wires, for
the terminals.
Do not block the cooling fan opening.
Do not disassemble the 2260B unless you are
qualified.
(Measurement categories) EN 61010-1:2010 and EN 61010-2-030
specify the measurement categories and their requirements as
follows. The 2260B falls under category II.
Measurement category IV is for measurement performed at the
source of low-voltage installation.
Measurement category III is for measurement performed in the
building installation.
Measurement category II is for measurement performed on the
circuits directly connected to the low voltage installation.
0 is for measurements performed on circuits not directly
connected to Mains.
Power Supply
WARNING
To avoid electrical shock connect the protective
grounding conductor of the AC power cord to
an earth ground.
Cleaning the
2260B
Disconnect the power cord before cleaning.
Use a soft cloth dampened in a solution of mild
detergent and water. Do not spray any liquid.
Do not use chemicals containing harsh material
such as benzene, toluene, xylene, and acetone.

Operation
Environment
Location: Indoor, no direct sunlight, dust free,
almost non-conductive pollution (Note below)
Relative Humidity: 20%~ 85%
Altitude: < 2000m
Temperature: 0°C to 50°C
(Pollution Degree) EN 61010-1:2010 and EN 61010-2-030 specify the
pollution degrees and their requirements as follows. The 2260B falls
under degree 2.
Pollution refers to “addition of foreign matter, solid, liquid, or
gaseous (ionized gases), that may produce a reduction of dielectric
strength or surface resistivity”.
Pollution degree 1: No pollution or only dry, non-conductive
pollution occurs. The pollution has no influence.
Pollution degree 2: Normally only non-conductive pollution
occurs. Occasionally, however, a temporary conductivity caused
by condensation must be expected.
Pollution degree 3: Conductive pollution occurs, or dry, non-
conductive pollution occurs which becomes conductive due to
condensation which is expected. In such conditions, equipment
is normally protected against exposure to direct sunlight,
precipitation, and full wind pressure, but neither temperature
nor humidity is controlled.

Disposal
Do not dispose this instrument as unsorted

facility or contact the supplier from which this
instrument was purchased. Please make sure
discarded electrical waste is properly recycled to
reduce environmental impact.

Power cord for the United Kingdom
When using the power supply in the United Kingdom, make sure
the power cord meets the following safety instructions.
NOTE: This lead/appliance must only be wired by competent persons
WARNING: THIS APPLIANCE MUST BE EARTHED
IMPORTANT: The wires in this lead are coloured in accordance with the
following code:
As the colours of the wires in main leads may not correspond with
the coloured marking identified in your plug/appliance, proceed
as follows:
The wire which is coloured Green & Yellow must be connected to
the Earth terminal marked with either the letter E, the earth symbol
or coloured Green/Green & Yellow.
The wire which is coloured Blue must be connected to the terminal
which is marked with the letter N or coloured Blue or Black.
The wire which is coloured Brown must be connected to the
terminal marked with the letter L or P or coloured Brown or Red.
If in doubt, consult the instructions provided with the equipment
or contact the supplier.
This cable/appliance should be protected by a suitably rated and
approved HBC mains fuse: refer to the rating information on the
equipment and/or user instructions for details. As a guide, a cable
of 0.75mm2 should be protected by a 3A or 5A fuse. Larger
conductors would normally require 13A types, depending on the
connection method used.
Any exposed wiring from a cable, plug or connection that is
engaged in a live socket is extremely hazardous. If a cable or plug is
deemed hazardous, turn off the mains power and remove the cable,
any fuses and fuse assemblies. All hazardous wiring must be
immediately destroyed and replaced in accordance to the above
standard.

Steps
1. 360W or 720W models:
Connect the power cord to
the rear panel socket.
1080W models: Connect
the power cord to the
universal power input.
2. Press the POWER key. If used for the first time,
the default settings will appear on the display,
otherwise The 2260B recovers the state right
before the power was last turned OFF.

OPERATION
Background
For most models the OVP level has a selectable
range of approximately* 10% to 110% of the
rated output voltage. Likewise the OCP level
for most models has a selectable range of
approximately* 10%~ 110% of the rated output
current. The OVP and OCP level is set to the
maximum by default. The OCP level can also
be turned off.
*Note that the actual setting range differs for
each model.
When one of the protection measures are on,
ALM is shown on the panel display. By
default, the power switch will turn off when
any of the protection levels are tripped.

Before setting the power supply to CV mode,
ensure:
The output is off.
The load is connected.
Steps
1. Press the Function key. The
Function key will light up.
2. The display should show F-

Set to CV Mode
When setting the power supply to constant voltage mode, a current
limit must also be set to determine the crossover point. When the
current exceeds the crossover point, the mode switches to CC mode.
CC and CV mode have two selectable slew rates: High Speed
Priority and Slew Rate Priority. High Speed Priority will use the
fastest slew rate for the instrument while Slew Rate Priority will
use a user-configured slew rate.

Background
Before setting the power supply to
CC mode, ensure:
The output is off.
The load is connected.
Steps
1. Press the Function key. The
Function key will light up.
2. The display should show F-
01 on the top and the
configuration setting for
F-01 on the bottom.
3. Rotate the Voltage knob to change
the F setting to F-03 (V-I Mode
Slew Rate Select).

Set to CC Mode
When setting the power supply to constant current mode, a voltage
limit must also be set to determine the crossover point. When the
voltage exceeds the crossover point, the mode switches to CV mode.
CC and CV mode have two selectable slew rates: High Speed
Priority and Slew Rate Priority. High Speed Priority will use the
fastest slew rate for the instrument while Slew Rate Priority will
use a user-configured slew rate.

Steps
1. Press the PWR/DSPL key. The
PWR DSPL key lights up.
2. The display changes to voltage and power
(V/W).
3. To switch between displaying A/W and V/W,
simply press the corresponding Voltage or

For example: when in A/W mode, press the
Voltage knob to display V/W. Conversely
when in V/W mode, press the Current knob to
display A/W.
