Basic Setting: Analyser Config; Type Of Electrical System Under Test; How To Set The Fundamental Frequency; How To Set The Current Range - MARTINDALE VR2250 User Instruction Manual

8.1. BASIC SETTING: ANALYZER CONFIG
Place the rotary switch in the ANALYSER position, press the MENU key, using the F1/F2
keys select the ANALYZER CONFIG item and press the ENTER Key.
The following screen will be displayed:
These settings can be confirmed by pressing the ENTER key or cancelled by pressing the
ESC key.

8.1.1. Type of electrical system under test

The parameter SYSTEM is fixed to "SINGLE" value as GENIUS 5080E is able only to
analyse a Single Phase system.

8.1.2. How to set the fundamental frequency

Position the cursor on the corresponding word by pressing the multifunction keys F1 and
F2 and select the network frequency between the possible values 50Hz and 60Hz by
pressing the multifunction keys F3 and F4. This parameter is important ONLY if the input
voltage is not sufficient to recognise the value of the frequency (for example, only the
clamps for the current measurement are connected). In this case the instrument generates
an internal synchronism equal to the value of the set frequency.

8.1.3. How to set the current range

The value of this parameter must always be equal to the full scale of the current
clamp used to take the measurement. If a multi-scale clamp is used, the value of this
parameter must be equal to the scale selected on the clamp.
Set the desired value by pressing the multifunction keys F3 and F4.

8.1.4. Clamp Type

The value of this parameter shows that only Standard clamps (STD) or Current
Transformers are available for this instrument. This parameter cannot be modified by the
user.

8.1.5. How to set the value of the transformer voltage ratio (TV RATIO)

The instrument can also be interfaced with step-down transformers in the equipment under
test. It can display the value of the voltages present on the primary winding of these
transformers. To do this it will be necessary to set the value of the transformers' windings
ratio from 2:1 to 3000:1. The default is set at 1:1 for measurements of none transformer
systems. Select "TV RATIO" in the ANALYZER CONFIG menu. Set the desired value by
pressing the multifunction keys F3 and F4.
