FAQs for ELF 3200 Series
2.2 How to change the meter setup?
Refer the QSG for ELF 3200 Series to enter and edit PROG menu - setup.
2.3What are WH and Wh in ELF3234?
Energy reading has 8-digit resolution. But the display will show four digits at a time. Generally the
higher digits (parameter will display capital "H". eg: VAH) are sufficient for monitoring. However if
lower digits (parameter will display small "h". eg: VAh) are required to be monitored in some
application, we can select the lower digit pages. Even in case of power failure, it automatically selects the
last displayed parameter and hence the selected parameter will be displayed.
For example: 12.345678 will be displayed as 12.34 in VAH ( KILO and MEGA LED OFF) and 5678
will display in VAh. Similarly 1234.5678 will be displayed as 1234. in VAH ( KILO and MEGA LED
OFF) and 5678 in VAh and also 12345.678 displayed as 12.34K (KILO LED is ON and MEGA LED is
OFF) in the VAH and 5678 in the VAh. (KILO and MEGA LED is OFF).
2.4. How do I use 96 x 48 mm compact size in already cut 96 x 96mm panel?
Adapter plate of 96 x 48 mm to 96 x 96 mm is available as optional accessory.
2.5 What are the wiring configurations possible with the ELF 3200 Series?
STAR 4V3A and DELTA 3V2A, which are selectable through the PROG menu.
2.6 What is the meaning of Star and DLTA in the PROG menu?
STAR means for STAR 3E, 4V3A (means for 3 phase 4 wire applications) and
DLTA means for DELTA 3E, 3V2A (for 3phase 3 wire applications).
Star is also called Wye in some countries.
2.7 Can I use ELF 3200 Series Meter for single-phase applications?
Yes. Please follow the steps below.
1.) Programme the meter in for STAR mode.
However Voltage primary and secondary needs to be programmed as Line to Line.
2.) Connect the voltage and current inputs only to the V1 and A1 voltage and current terminals of the meter.
3.) The unused current terminals (A2 and A3) must be shorted together.
NOTE: Please refer V1 and A1 only for correct readings in ELF 3259.
2.8 How to check for wrong connections?
These steps are applicable for both Star and Delta systems.
1.) If the current in any phase is reversed (instead of S1 to S2 the connection is S2 to S1), Active power of
W1, W2, W3 shows negative (for ELF 3234 and ELF 3234-3). However, in ELF 3259 it is not possible to
identify reversed current connections.
Reverse the current inputs of the phase, which shows the W negative (ELF 3234 and ELF 3234-3).
2.) For checking the System (Star or Delta) for the sequence of connection
• Connect all the voltages and auxiliary supply.
• Connect the current from R and B phase. Switch ON the meter.
• For ELF 3234 and ELF 3234-3: If the System is STAR then Y phase current and power parameter is zero,
else if the System is DLTA then Y phase current and power parameter will display some value.
• For ELF 3259: If the System is STAR then Y phase current is zero, else if the System is DLTA then Y
phase current will display some value.
2.9 When do I need to connect an external CT/PT?
External CT is required when the current to be measured is greater than 6A.
An external PT is required when voltage greater than 500V (Phase – Phase).
2.10 Is it possible to use ELF 3200 Series Meter without CT application (i.e. load
