Note
If you replace the battery please use original spare parts only – see
section “Standard and Optional Accessories”.
Maintenance
If the Logger is used appropriately it does not require special maintenance or
repair. If the Logger gets dirty wipe it off carefully with a damp cloth (without
cleaning agents). Maintenance work may be executed only by trained and
qualified personnel. This work may only be done at a company related service
center within the guarantee period. See www.fluke.com for locations and
contact information of Fluke Service Centers worldwide.
Calibration
As an additional service we offer the regular examination and calibration of
your Logger.
Storage
If the Logger is stored for longer time or is not in use for longer time, you
should charge the battery at least once every six months.
Measurement Theory
The following formulas are the basics of the measuring values:
Voltage and current measurement
VRMS =
1 2
v dt
T∫
RMS value of voltages
I RMS =
1 2
i dt
T∫
RMS value of currents
I N = I1 + I 2 + I 3
RMS value of neutral-conductor current
Neutral is calculated when not measured, i.e., no 4phase Flexi set is connected.
