Getting Started Manual

WA-GSM-E RevB

CAUTION

Do not exceed the maximum specified front panel terminal CH1, CH2 (or CH3 and CH4 on 4 channel models), and EXT TRIG voltage levels. Refer to Specifications for more details.

Safety Certification

The design of the instrument has been verified to conform to applicable EN 61010-1, UL 61010-1 2nd Edition and CSA C22·2 No·61010-1-04 safety standards for the following limits:

 Installation (Overvoltage) Categories II (Mains Supply Connector) & I

(Measuring Terminals).

 Pollution Degree 2.  Protection Class I.

PLEASE NOTE THE FOLLOWING:

 Installation (Overvoltage) Category II refers to local distribution

level, which is applicable to equipment connected to the mains supply (AC power source).

 Installation (Overvoltage) Category I refers to signal level, which is

applicable to equipment measuring terminals that are connected to source circuits in which measures are taken to limit transient voltages to an appropriately low level.

 Pollution Degree 2 refers to an operating environment where

normally only dry non-conductive pollution occurs. Conductivity caused by temporary condensation should be expected.

 Protection Class 1 refers to grounded equipment, in which

protection against electric shock is achieved by Basic Insulation and by means of a connection to the protective ground conductor in the building wiring.

Cooling

The instrument relies on forced air cooling with an internal fan and ventilation openings. Care must be taken to avoid restricting the airflow around the apertures (fan holes) at the sides of the oscilloscope.

WaveAce Series

WA-GSM-E RevB

Ensure adequate ventilation by leaving the required 5 cm (2 inch) minimum gap around the sides of the instrument.

CAUTION

Do not block the ventilation holes located on both sides of the oscilloscope.

CAUTION

Do not allow any foreign matter to enter the oscilloscope through the ventilation holes, etc.

AC Power Source

100 to 240 VAC (+/-10%) at 50/60/400 Hz (+/-5%);Installation Category: 300V CAT II

No manual voltage selection is required because the instrument automatically adapts to line voltage.

Power Consumption

< 50 Watts for all models (depending on accessories installed - probes, USB devices, etc.).

Power consumption in Standby Mode: <5 Watts.

Power and Ground Connections

The instrument is provided with a 10A/250V 18AWGrated grounded cord set containing a molded three-terminal polarized plug and a standard IEC320 (Type C13) connector for making line voltage and safety ground connections. The AC inlet ground terminal is connected directly to the frame of the instrument. For adequate protection against electrical shock hazard, the power cord plug must be inserted into a mating AC outlet containing a safety ground contact.

Getting Started Manual

WA-GSM-E RevB

WARNING - Electrical Shock Hazard

Only use the power cord provided with your instrument. Any interruption of the protective conductor inside or outside of the

oscilloscope, or disconnection of the safety ground terminal creates a hazardous situation. Intentional interruption is prohibited.

In Standby mode, the oscilloscope is still connected to the AC supply. The instrument can only be placed in a complete Power Off state by physically disconnecting the power cord from the AC supply or by flipping the main power switch on the back of the oscilloscope to the off (Zero) position (on 4 channel models).

CAUTION

The outer shells of the front panel terminals CH1, CH2 (or CH3 and CH4 on 4 channel models), and EXT TRIG are connected to the instrument’s chassis and therefore to the safety ground.

Fuse Replacement

(4 Channel Models Only) Set the instrument Standby (power) switch to Standby mode, flip the

mains power switch to the OFF (0) position, and disconnect the power cord before inspecting or replacing the fuse. Open the black fuse holder (located at the rear of the instrument below the main power switch) using a small, flat-bladed screwdriver.
