Analyser - MARTINDALE VR2250 User Instruction Manual

8. ANALYSER

This function allows the following operations:
Display in real time the electrical parameters of a single phase system (with and
without neutral wire) and the harmonic analysis of voltage and current.
Conduct a direct Energy measurement (without memorizing).
Memorize (pressing SAVE key) the sampled values of the Parameters present at the
instrument input generating a "Smp" record inside the instrument memory. It will be
possible to analyse the memorized data ONLY by transferring the data to a PC.
Record simultaneously (pressing the START key after a proper setting): RMS values
of voltage, current, corresponding harmonics, active, reactive and apparent powers,
power factors and cos ϕ , active, reactive and apparent energies, voltage anomalies
(voltage sag and surge) with 10ms resolution. It will be possible to analyse the
recorded data ONLY by transferring the data to a PC.
Record simultaneously (pressing the START key) values of Voltage and Current
values coming from test leads and Clamp, using "Typical Configurations" with pre-
programmed parameters inside the meter (see paragraph 10.2 ).It will be possible to
analyse the recorded data ONLY by transferring the data to a PC.
It's fundamental the Instrument settings correspond to the Installation type under test and
accessories in use. For this we recommend the user checks the instrument's settings
before executing an ANALYSIS measurement.
Select the ANALYSER position on the rotary switch. By pressing the MENU key the
following screen will be displayed:
It's not possible to enter the MENU during a recording or a Real Time Energy
measurement.
Generally to check instrument's settings you must check "ANALYZER CONFIG" and
"RECORDER CONFIG" items.
