Multiplying Factor (MF)
In the case of Direct Reading Meters, Multiplying Factor is the number by which Counter reading must be multiplied to get actual
kWh consumed. The MF is indicated by decimal point of the Meter. In the case of 3 Phase 4 Wire Model DM 5240, calibrated for
415V/5A, the decimal point printed on the meter is 0.01. Each count on the Counter represents 1/100th of a kWh for direct input
of 415V/5A. For the same meter when input is through a CT, depending on the CT Ratio an additional MF has to be applied by the
user to get actual consumption. For example, for a CT Ratio of 100/5, the consumption is given by (Counter Reading) x 0.01 x
100/5 i.e, (Counter Reading) x 0.2. Thus, for a 500/5 CT, the Counter Reading directly gives the consumption.
What do the POWER & INTEG LEDs on the front panel do ?
POWER LED indicates presence of Auxiliary Power which is essential for the meter operation.
INTEG LED indicates that integration of Energy is in progress. The LED Blink Rate is either 10 or 8 times that of the Counter update.
Hence its resolution is 10 or 8 times that of the Counter and can be conveniently used for meter calibration.
Overflow Hours?
As the Counter accumulates kWh, it will eventually reach 999999 and then overflow to 000000. The duration it takes to overflow is
approximately equal to (999999) / average kW which the meter senses.
TAMPER PROOF COVER OPTION
A Tamper Proof cover enables sealing of terminal block at the rear of the meter. This prevents tampering of connections.
Pulse Output Feature
Optically Isolated, Solid-state NO Contact gives digital pulse output to drive Remote Counter, PLC, DCS Station etc. for off line
monitoring of Energy Data, on line control for Energy/Power/Process optimisation, correlating Energy Input to product output
etc. Applications of pulse output feature are as shown below.

Pulse output from DM 52 can be
integrated into a process through a
PLC/DCS for online control of
Energy content in a process.
If the DCS/PLC has a self excited
12V or 24V Digital Input, external
24V DC Supply is not needed.
The kWh pulses may also be used to
derive average kW information at
the PLC

configured to record Data shiftwise, day wise etc., while DM 52
records total consumption.
Several DM 52s can be networked
into a cost effective centralised
system to centrally monitor energy
data and generate a variety of
reports covering load-wise, shiftwise, day-wise or batch-wise
analysis of energy consumption.
