Fluke 345 Technical Data Manual page 2

Applications
Set up and troubleshoot variable frequency drives
and UPS systems - Verify correct operation by
measuring key parameters
Harmonics measurements - Uncover harmonic issues
that can damage or disrupt critical equipment
Inrush capture - Check start-up current where spurious
resets or nuisance circuit breaker tripping occurs
Load studies - Verify electrical system capacity
before adding loads
Log measured parameters
All voltage, current, power, and harmonic measurements
can be logged for minutes, hours, or months. Measurement
averaging periods from 1 second to 15 minutes can be selected
depending on the application.
Measured parameters can be logged into three separate
recording memory areas. If longer recordings are required, the
three areas may be combined into one. Stored measurements
can be recalled and displayed on-screen in normal screen
format or downloaded using the Power Log software package.
