Safety Notices
General Considerations
Please review the following safety precautions carefully before putting your
instrument into operation so as to avoid any personal injuries or damages to the
instrument and any product connected to it. To prevent potential hazards, please use
the instrument in compliance with regulations of this manual.
Use Proper Power Cord
Only the power cord designed for the instrument and authorized by local country
could be used.
Ground the Instrument
The instrument is grounded through the Protective Earth lead of the power cord. To
avoid electric shock, it is essential to connect the earth terminal of the power cord to
the Protective Earth terminal before any inputs or outputs.
Connect Test Leads Correctly
The test leads must be connected in strict accordance with regulations in this guide.
Observe all Terminal Ratings
To avoid fire or shock hazard, observe all ratings and markers on the instrument and
check your manual for more information about ratings before connecting.
Use Proper Overvoltage Protection
Make sure that no overvoltage (such as those caused by a thunderstorm) can reach
the product, or else the operator might expose to danger of electrical shock.
Do Not Operate Without Covers
Do not operate the instrument with covers or panels removed.
Use Proper Fuse
Please use the specified fuses.
Avoid Circuit or Wire Exposure

RIGOL
User’s Guide for DP1116A
III
Do not touch exposed junctions and components when the unit is powered.
Do Not Operate With Suspected Failures
If you suspect damage occurs to the instrument, have it inspected by qualified service
personnel before further operations. Any maintenance, adjustment or replacement
especially to circuits or accessories must be performed by RIGOL authorized
personnel.
Keep Well Ventilated
Inadequate ventilation may cause an increase of temperature or damage to the
device. So please keep well ventilated and inspect the intake and fan regularly.
Do Not Operate in Wet Conditions
In order to avoid short circuiting to the interior of the device or electric shock, please
do not operate in a humid environment.
Do Not Operate in an Explosive Atmosphere
In order to avoid damages to the device or personal injuries, it is important to
operate the device away from an explosive atmosphere.
Keep Product Surfaces Clean and Dry
To avoid the influence of dust or moisture in air, please keep the surface of device
clean and dry.
Electrostatic Prevention
Operate in an electrostatic discharge protective area environment to avoid damages
induced by static discharges. Always ground both the internal and external
conductors of the cable to release static before connecting.
Handling Safety
Please handle with care during transportation to avoid damages to buttons, knob,
interfaces and other parts on the panels.

First Use of DP1116A
Prior to making any connections to the instrument, read the section of “General
Inspection”carefully to avoid any possible or potential dangers and carry out
necessary check and inspections following the requirements below when you first
use the DP1116A.
Power Requirements
Use the power cord that is specifically designed for the DP1116A to connect the
instrument and the AC power which delivers 100 V, 115 V, 220 V or 230 V, 50 Hz to 60
Hz. Users should select a voltage scale that meets the standards in their own country
through the Power voltage selector (see Figure 1-2) at the rear panel and use an
appropriate fuse.
Note:
250 V, T4 A fuse: 100 V and 115 V
250 V, T2.5 A fuse: 220 V and 230 V
To change the voltage scale of the instrument, please:
1. Turn off the power switch/button at the front/rear panel and remove the power
cord.
2. Check if the fuse installed before leaving factory (250 V, T2.5 A) can match with
the selected voltage scale; if not, change it.
3. Regulate the voltage selector to a desired scale using a straight screwdriver.
