set voltage and ensure that the instrument voltage corresponds to the intended supply voltage.
Important: The wires in the power lead fitted to mains instruments are coloured in accordance with
the following code:
Green

instruments for use on mains power can operate on either a 230V or 115V
50/60Hz AC supply.
Instruments are factory pre-set to operate from the mains voltage specified at time of ordering.
If, for any reason, the user needs to change the mains operating voltage the following procedure
must be adhered to:
1.
Disconnect the Mains Supply.
2.
Gently prise off the front panel bezel surround and allow the front panel to fall forward
and out.
3.
Remove the two nuts at the rear of the case, then push the instrument out through the
case front.
4.
Pads which select the operating voltage are located on the under side of the printed
circuit board. The existing link(s) should be removed and new link(s) should be soldered
across the appropriate pads, and the instrument reassembled (one link is used for 230V
AC, two links are needed for 115V AC).
