GDS-1000-U Series User Manual SAFETY INSTRUCTIONS This chapter contains important safety instructions that should be followed when operating and storing the oscilloscope. Read the following before any operation to ensure your safety and to keep the oscilloscope in the best condition. Safety Symbols These safety symbols may appear in this manual or on the oscilloscope. WARNING Warning: Identifies conditions or practices that could result in injury or loss of life.
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. Safety Guidelines General Guideline CAUTION Make sure the BNC input voltage does not exceed 300V peak. Never connect a hazardous live voltage to the ground side of the BNC connectors. It might lead to fire and electric shock. Do not place heavy objects on the oscilloscope.
GDS-1000-U Series User Manual Power Supply WARNING Fuse WARNING Cleaning the oscilloscope Operation Environment AC Input voltage: 100 ~ 240V AC, 47 ~ 63Hz The power supply voltage should not fluctuate more than 10%. Connect the protective grounding conductor of the AC power cord to an earth ground. Fuse type: T1A/250V To ensure fire protection, replace the fuse only with the specified type and rating. Disconnect the power cord before replacing the fuse.
SAFETY INSTRUCTIONS (Pollution Degree) EN 61010-1:2001 specifies pollution degrees and their requirements as follows. The oscilloscope 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.

Moving the waveform position horizontally Procedure The horizontal position knob moves the waveform left or right. The position indicator at the top of the display shows the center and current position.
CONFIGURATION Selecting the waveform update mode Background The display update mode is switched automatically or manually according to the horizontal scale. Main mode Updates the whole displayed waveform at once. The main mode is automatically selected when the horizontal scale (timebase) is fast. Roll mode Horizontal scale ≤100ms/div Trigger All modes available Updates and moves the waveform gradually from the right side of the display to the left.

FAQ FAQ • The input signal does not appear in the display. • I want to remove some contents from the display. • The waveform does not update (frozen). • The probe waveform is distorted. • Autoset does not catch the signal well. • Autoset function cannot catch signals under 30mV or 30Hz. Please use the manual operation. See page46 for details. I want to clean up the cluttered panel settings. • The accuracy does not match the specifications. The input signal does not appear in the display.
GDS-1000-U Series User Manual The waveform does not update (frozen). Press the Run/Stop key to unfreeze the waveform. See page 47 for details. For trigger setting details, see page 84. If this does not help, press the CH key. If the signal still does not appear, press the Autoset key. The probe waveform is distorted. You might need to compensate the probe. For details, see page 117.
FAQ The accuracy does not match the specifications. Make sure the device is powered on for at least 30 minutes, within +20°C~+30°C. This is necessary to stabilize the unit to match the specification.
