RISH Master 3480 - Touch Screen Graphics LCD
Touch screen graphics LCD
Rish Master 3480 has touch sensible color graphics LCD display with resolution of 320x240.
On site programmable PT/CT ratios
It is possible to program primary of external potential Transformer (PT), primary of external Current Transformer (CT) on site locally by entering into Programming mode or remotely via MODBUS (RS485)
User selectable CT Secondary 5A/1A
The secondary of external Current Transformer (CT) can be programmed on site to either 5A or 1A locally by entering into Programming mode or remotely via MODBUS (Rs485)
User selectable PT Secondary
The secondary of external potential Transformer (PT) can be programmed on site locally by entering into programming mode or remotely via MODBUS (RS485)
User selectable 3 phase 3W or 4W unbalanced network
User can program on site the network connection as either 3 Phase 3 Wire or 4 Wire locally by entering into Programming mode or remotely via MODBUS (RS485). For single phase applications, single phase version is available.
Low back depth
The instrument has very low back depth (behind the panel) of less than 80 mm in spite of optional features like pulse output
Onsite selection of Auto scroll / Fixed Screen
User can set the display in auto scrolling mode or fixed screen mode can be programmed locally by entering into Programming mode or remotely via MODBUS (RS485).
Phase reversal indication
The instrument can detect wrong phase sequence or failure of one of the input voltages and displays “phase” error message.
Energy measurement (Import and Export)
Active energy (kWh), Reactive energy (kVArh), Apparent energy (kVAh) & Ampere Hour (kAh). Any of the parameters can be freely assigned to 2 optional pulse outputs.
True RMS measurement
The instrument measures distorted waveform up to 15th Harmonic.
User selectable Low Current suppression (below 30 mA)
User can suppress the readings below 30 mA in the current measurement by onsite programming if required.
Min Max storage of parameters possible
The instrument stores minimum and maximum values for System Voltage and System Current. Every 40 sec minimum and maximum readings are updated.
Number of parameters measured: more than 46
The instrument measures more than 46 electrical parameters of 3 Phase network.
Parameter Screen recall
In case of power failure, the instrument memorizes the last displayed screen. The displayed screen will get memorized only if user keeps this screen for minimum 40 sec duration before power failure for fixed screen mode.
