Category rating
The IEC 61010 standard denes safety category ratings that specify the amount of electrical energy available and the voltage impulses that may occur on electrical conductors associated with these category ratings. The category rating is a Roman numeral of I, II, III, or IV. This rating is also accompanied by a maximum voltage of the circuit to be tested, which denes the voltage impulses expected and required insulation clearances. These categories are:
Category I (CAT I): Measurement instruments whose measurement inputs are not intended to be connected to the
mains supply. The voltages in the environment are typically derived from a limited-energy trans­former or a battery.
Category II (CAT II): Measurement instruments whose measurement inputs are meant to be connected to the mains
supply at a standard wall outlet or similar sources. Example measurement environments are portable tools and household appliances.
Category III (CAT III): Measurement instruments whose measurement inputs are meant to be connected to the mains
installation of a building. Examples are measurements inside a building’s circuit breaker panel or the wiring of permanently-installed motors.
Category IV (CAT IV): Measurement instruments whose measurement inputs are meant to be connected to the primary
power entering a building or other outdoor wiring.
Do not use this instrument in an electrical environment with a higher category rating than what is specied in this manual for this instrument.
You must ensure that each accessory you use with this instrument has a category rating equal to or higher than the instrument’s category rating to maintain the instrument’s category rating. Failure to do so will lower the category rating of the measuring system.
Electrical Power
This instrument is intended to be powered from a CATEGORY II mains power environment. The mains power should be 115 V RMS or 230 V RMS. Use only the power cord supplied with the instrument and ensure it is appropriate for your country of use.
Ground the Instrument
To minimize shock hazard, the instrument chassis and cabinet must be connected to an electrical safety ground. This instrument is grounded through the ground conductor of the supplied, three-conductor AC line power cable. The power cable must be plugged into an approved three-conductor electrical outlet. The power jack and mating plug of the power cable meet IEC safety standards.
Do not alter or defeat the ground connection. Without the safety ground connection, all accessible conductive parts (including control knobs) may provide an electric shock. Failure to use a properly-grounded approved outlet and the recommended three-conductor AC line power cable may result in injury or death.
3
Unless otherwise stated, a ground connection on the instrument’s front or rear panel is for a reference of potential only and is not to be used as a safety ground. Do not operate in an explosive or ammable atmosphere.
Do not operate the instrument in the presence of ammable gases or vapors, fumes, or nely-divided particulates.

Do not touch live circuits
Instrument covers must not be removed by operating personnel. Component replacement and internal adjustments must be made by qualied service-trained maintenance personnel who are aware of the hazards involved when the instrument’s covers and shields are removed. Under certain conditions, even with the power cord removed, dangerous voltages may exist when the covers are removed. To avoid injuries, always disconnect the power cord from the instrument, disconnect all other connections (for example, test leads, computer interface cables, etc.), discharge all circuits, and verify there are no hazardous voltages present on any conductors by measurements with a properly-operating voltage-sensing device before touching any internal parts. Verify the voltage-sensing device is working properly before and after making the measurements by testing with known-operating voltage sources and test for both DC and AC voltages. Do not attempt any service or adjustment unless another person capable of rendering rst aid and resuscitation is present. Do not insert any object into an instrument’s ventilation openings or other openings.
Hazardous voltages may be present in unexpected locations in circuitry being tested when a fault condition in the circuit exists.
Fuse replacement must be done by qualied service-trained maintenance personnel who are aware of the instrument’s fuse requirements and safe replacement procedures. Disconnect the instrument from the power line before replacing fuses. Replace fuses only with new fuses of the fuse types, voltage ratings, and current ratings specied in this manual or on the back of the instrument. Failure to do so may damage the instrument, lead to a safety hazard, or cause a re. Failure to use the specied fuses will void the warranty.

1. Press Waveforms → Ramp → Symmetry, to set the symmetry. The symmetry shown on the screen when the instrument is powered on is the default value or the set value of last power down.
2. Input the desired Symmetry.
Use the numeric keyboard to input the parameter value directly, and press the corresponding key to select the parameter unit. Or use the arrow keys to select the digit to edit, and then use the knob to change its value. The generator will change the waveform immediately.

Pulse Wave
Press Waveforms key to select the waveform function, and press the Pulse softkey. The pulse waveform parameters are set by using the pulse operation menu. The parameters for pulse waveforms include frequency/period, amplitude/high level, oset/low level, width, rise/fall and delay. As shown in Figure 5.1, in the soft key menu, select PulWidth. The pulse width parameter area is highlighted in the parameter display window, and users can set the pulse width value here.
Figure 5.1 Pulse Waveform Main Screen
Frequency/ Period Set the signal frequency or period; The current parameter will be switched at a second press.
Amplitude/ HighLevel Set the signal amplitude or high level; The current parameter will be switched at a second press.
Oset/ LowLevel Set the signal oset or low level; The current parameter will be switched at a second press.
PulWidth/ DutyCycle Set the signal pulse width or duty cycle; The current parameter will be switched at a second press.
Rise/ Fall Setting the rise edge or fall edge for pulse waveform. The current parameter will be switched at
a second press.
Delay Setting the delay for pulse waveform.
5.1 Frequency, Amplitude, Oset, High/Low level, and Phase
Set the frequency, amplitude, high level, low level, and oset as shown in Figures 4.2, 4.3, 4.4, 4.5, 4.6.
5.2 Pulse Width and DutyCycle
Pulse width is dened as the time from the 50% threshold of a rising edge amplitude to the 50% threshold of the next falling edge amplitude (as shown in the gure below). The pulse width setting range is limited by the “Minimum Pulse Width” and “Pulse Period” setting. For detailed information, please refer to “4060B Series Datasheet”. The default value is 200s. Pulse duty cycle is dened as the percentage that the pulse width takes up in the whole period. Pulse duty cycle and pulse width are correlative. Once a parameter is changed, the other will be automatically changed.
1. Press Waveforms→ Pulse → PulWidth, to set the pulse width. The pulse width shown on the screen when the instrument is powered on is the default value or the set value of last power down. If you want to set the waveform by duty, press the PulWidth/DutyCycle key again, to switch into the duty parameter (the current operation is displayed in inverse color).

2. Input the desired Pulse Width.
Use the numeric keyboard to input the parameter value directly, and press the corresponding key to select the parameter unit. Or use the arrow keys to select the digit to edit, and then use the knob to change its value. The generator will change the waveform immediately.
5.3 Rising and Falling Edges
Rise edge time is dened as the duration of the pulse amplitude rising from 10% to 90% threshold, while fall edge time is dened as duration of the pulse amplitude moving down from 90% to 10% threshold. The setting of rise/fall edge time is limited by the currently specied pulse width limit. Users can set rise edge and fall edge independently.
1. Press Waveforms → Pulse → Rise to set the rise edge. The rise edge shown on the screen when the instrument is powered on is the default value or the set value of last power down. If you want to set the waveform by fall edge, press the Rise/Fall key again, to switch into the fall edge parameter (the current operation is displayed in inverse color).
2. Input the desired rise edge.
Use the numeric keyboard to input the parameter value directly, and press the corresponding key to select the parameter unit. Or use the arrow keys to select the digit to edit, and then use the knob to change its value. The generator will change the waveform immediately.
