Preventive Maintenance
Cleaning
Disconnect the instrument and wipe it with a clean cloth
slightly
damped with soapy water or Isopropyl alcohol (IPA). Care should
be taken near the terminals, IEC power and USB sockets.
Care of the instrument
The instrument should always be handled with care and not
dropped. Always ensure that the instrument is secured when
being transported to prevent mechanical shock.
Leads
Leads are silicone insulated and perform well in all weather
conditions. Always keep the leads in the clip-on lead pouch
supplied with the instrument.
Regular inspection of leads is recommended to ensure they are
not damaged in any way. Damaged leads could affect insulation
resistance readings and are a safety hazard.
Battery Care
The battery should be charged on a routine basis at an absolute
minimum of once a year. However more regular charging, i.e.
once per quarter is preferable.
Never attempt to charge the battery below 0 °C or above +40 °C.
The battery is charged by connecting line power at the instrument
IEC power socket.
Store the instrument in a cool, dry location to improve battery life.
Storage temperatures below freezing should be avoided.
Replacing the battery
Read and fully understand the warnings on the Li-ion battery in the
Safety Warnings section of this document.
Switch the instrument OFF, and disconnect the mains supply,
measurement leads, and all other equipment before opening the
case to change the battery. The instrument must not be operated
with the case open. DANGER! Hazardous voltages are exposed with
the mains connected and the case open.
The battery pack contains Lithium-ion cells and should be replaced
when it no longer holds a charge. A new battery is available as a
spare part from Megger.
Genuine Megger battery packs must be
used. Failure to use genuine parts may affect product safety
performance and will invalidate your warranty.
Replacement involves removal of four screws from the bottom of the
instrument after which the base can be lifted away from the front
panel and internal moulded assembly. Care should be taken to keep
the front panel and moulding assembly together. The battery pack is
housed within a grey moulded cover secured by four screws.
S1-568, S1-1068 battery replacement instructions:
1. Switch the instrument OFF, and disconnect the AC supply,
measurement leads, and all other equipment before opening
the case to change the battery.
2. The instrument must not be operated with the case open.
DANGER! Hazardous voltages are exposed with an AC
source connected and the case open.
3. Remove the lid and invert the lower case resting the front
panel on a soft surface so as not to damage the keypad.
4. Remove the four case fixing screws and lift off case bottom.
5. Carefully unclip the battery cable connector leading from the
main printed circuit board to the battery and remove the
cables from recesses designed to hold them in place.
6. Remove the four screws and lift off the battery cover.
