equipment may affect other equipment: PCs, laptops, tablets and mobile phones may be affected.
Warnings:
For your safety, this product should be used in accordance with these instructions, otherwise the protection
provided may be impaired.
Do not open or remove covers or panels. Repairs and service may only be carried out by our repair agent,
otherwise the warranty may be void.
Use only the 3-core mains cable supplied with the unit. If the mains cable is replaced, the rating of the
replacement must be the same or better than the original.
The unit must be earthed at all times. The unit is earthed/grounded through the 3-core mains lead, so no
additional earth connection is required.
Always position the generator so that it can be disconnected from the mains, if an emergency arises.
This unit is intended for use in DRY conditions. Avoid spillage of water and other liquids on to the unit. If
spillage occurs, disconnect the mains supply.
There is no specific requirement for insulation of external circuits as they cannot become hazardous live, as a
result of connection to this unit. Limit the length of any connecting leads to 3 metres.
Purpose:
A robust, basic instrument for general laboratory use. The
output is suitable for input to oscilloscopes and small
loudspeakers. An internal speaker makes it useful for small
group work in sound.
Output:
Sine and square waveforms.
Frequency range 10Hz to 110kHz in 4 decades.
Accuracy 2%, distortion less than 0.5% at 1kHz sine.
2V rms (5.6V peak to peak) into a 100 ohm
load Frequency response 10Hz to 110kHz
Output impedance 100 ohm.
Ratings:
230V ac +/-10% 50Hz
40VA
Fuse: F50mA
Temperature range: 10 to 40°C
Humidity: 10 to 90%

EMC:
This equipment is Class A according to the EMC standard EN55011
and is intended for use in a non-domestic environment only.
Interference from nearby sources of RFI (radio frequency
interference) may affect the output signals. Likewise, this

- Page 3 In the unlikely event of the fuse blowing, the retainer and mains cable must be removed to gain access to the fuse carrier. The carrier can be removed with a fingernail or tip of a screwdriver. A spare fuse is provided in the carrier. Replacement fuses must be 20mm cartridge fuses, of the correct rating : F50mA Cleaning The front panel membrane conceals and protects switches and LEDs.
