Safety This instrument is Safety Class I according to IEC classification and has been designed to meet the requirements of EN61010-1 (Safety Requirements for Electrical Equipment for Measurement, Control and Laboratory Use). It is an Installation Category II instrument intended for operation from a normal single phase supply. -
Page 7: Installation
Installation Mains Operating Voltage The operating voltage of the instrument is shown on the rear panel. Should it be necessary to change the operating voltage from 230V to 115V or vice-versa, proceed as follows: Disconnect the instrument from all voltage sources. Unclip the front bezel by gently pulling the centre of each long edge up and forward. -

General Service Handling Precautions Service work or calibration should only be carried out by skilled engineers using high quality test equipment. If the user is in any doubt as to his competence to carry out the work, the instrument should be returned to the manufacturer or their agent overseas for the work to be carried out. This simplified service guide only details the routine calibration procedure and the dismantling of the instrument to PCB assembly level. - Page 9 The MAIN PCB may be removed as follows. With the case and front panel assembly removed, the MAIN PCB is left connected to the rear panel metalwork. This can be separated by removing the nut that secures the green/yellow safety earth cable to the rear panel.
