- Small size, low weight, portable instrument.
- True R.M.S. measuring system.
- Instantaneous, maximum and minimum values of each discrete electric
parameter.
- Electrical energy meters incorporated
- Harmonic measurement
- Neutral current measurement (only in AR5-L model)
- RS-232 communication to PC
- Ability of setting a recording threshold, so that data is only recorded in
memory when measured values are not within the defined threshold (see
Section 6.1.2.2.-TRIGGER: Trigger conditions).
- Automatic data collection in memory at regular user-definable periods.
Depending on the type of circuit under analysis, following enumerated
parameters are measured and can be saved in memory:
NOTE: It’s not allow to save cos
ϕ
data in memory. Only can be read on
display.
