Iskra MT382-CT-MID approved meter is targeted at deregulated energy markets and enables provision of an AMR service. It is a polyphase meter intended for use in Commercial/Industrial and CoP5 applications. The meter incorporates a fully integrated GSM modem. The integrated GSM modem can be exchanged with integrated RS485 communication interface for multisite installations. It is a perfect combination of well-proven metering technology and state-of-the-art GSM communication modem, all integrated and sealed in a single enclosure. The integrated solution attains the same high quality and reliability of Iskraemeco meters. The meter is approved according to IEC 62052-11 and IEC 62053-21, ISO 9001, and designed according to even higher internal Iskraemeco standards, based on 60 years of experience of meter manufacturing and more than 55 million meters installed worldwide.
Reading the Meter:
The MT 382 display will auto scroll to show the required readings.
Normally this will only be 1.8.0 Positive Kwh (A+).
Note: No buttons need to be pressed during normal operation of the meter.
The BLUE button can be used to manually scroll through additional readings for information and diagnostic purposes.
The OBIS code appears in the left of the display and the relevant reading on the right.
Reading the Display:
Auto scroll has the following OBIS codes:
1.8.0 A+ Positive active Energy (Kwh)
Manual Scroll is access by pressing the BLUE button sequentially.
Each press of the BLUE button will scroll to the next reading which is identified by the OBIS code (shown below).
C.1.0 Manufacturing Number
U.20.0 GSM Signal Strength
U.20.1 GSM Status
0.9.1 Time of day
1.8.0 A+ Positive active energy, total
2.8.0 A- Negative active energy, total
1.7.0 A+ instantaneous power (W)
31.7.0 Instantaneous current in phase L1 (A)
51.7.0 Instantaneous current in phase L2 (A)
71.7.0 Instantaneous current in phase L3 (A)
32.7.0 Instantaneous voltage (U) in phase L1
52.7.0 Instantaneous voltage (U) in phase L2
72.7.0 Instantaneous voltage (U) in phase L3
When you’ve reached end of sequence, let the display time out and the meter will return to auto scroll mode.
