The Miro is intended to be used on energised lines or equipment. Personnel using
equipment on energised lines must be authorised by the relevant regulatory bodies to carry
out such work and must have appropriate training.
The information given in this document is given as a guide only. It is the user's responsibility
to ensure that correct and safe procedures are followed at the actual work site. CHK Power
Quality Pty Ltd offers no warranty or indemnity for accidents that may occur when following
these instructions.
Prior to using a Miro, you should note the following:
The voltage leads have internal field replaceable HRC fuses. Refer to Section 10.6
on troubleshooting if you suspect a blown fuse.
If the Miro and accessories are used in a manner not specified in this manual, the
protection provided by the equipment may be impaired.
The Miro should not be immersed in water or other fluids. The Miro should not be
used in explosive atmospheres.
When any voltage clamp/plug is connected to a hazardous live conductor, the other
voltage clamp/plugs should also be treated as live, due to the internal measurement
impedance of the Miro.
Connectors should be properly connected to their receptacles, using their screw or
push fastener
The outer sheath of all leads should be free from damage, with no inner insulation
showing. There should be no breakages or cracks in the Miro enclosure, the voltage
clamps, banana plugs or connectors.
The Miro is suitable for outdoor measurements only when used with the
recommended voltage leads. When other voltage leads are used, the unit is suitable
for indoor measurements.
When used outdoors with the recommended voltage leads, the unit will withstand
exposure to rain and fog.
All voltage leads and current probes should be connected to the Miro before
connection to mains conductors.
Any equipment showing signs of damage should not be used. Return it to CHK
Power Quality Pty Ltd.
