200G Ohm Insulation Meter for Planned Shutdowns
Answer first: A 200G ohm insulation meter for planned shutdowns lets one shared instrument cover high readings across motors, cables and switchgear in the outage window.
Shutdown planning
Outage weeks compress testing. Teams without a wide-range 5 kV meter either skip assets or queue on a single premium brand tool.
Listing the AP-6688B at £106.16 gives managers a budget path to put a second or shared unit on the shutdown cart.
Evidence for maintenance records
Capture voltage used, reading, temperature and humidity notes per your procedure—raw megohms without context are hard to trend.
Frequently asked questions
Why cite 200 GΩ?
It is the upper window on this class of meter—useful when insulation is healthy and high.
One meter for the whole site?
Possible for SMEs; larger plants often need multiples to avoid waiting.
Training
Brief the crew on voltage selection so LV assets are not over-tested.
Procurement checks
Confirm tax, delivery, returns and whether calibration docs are required for ISO audits.
