1.2 Foreword
Thank you for purchasing the DMMetering PRO1250 SERIES DIN rail three phase
four wire energy meter. The DMMetering PRO1250 SERIES energy meter is the
most advanced type electronic kWh meter available at the market. With the
DMMetering product range we have introduced a large scale of energy meters on
the market suitable for 110V AC to 400V AC (50 or 60Hz). Besides the normal
energy meters we also developed our own pre-paid meters with chip card, chip card
re-loaders and a complete PC management control system. For more information
on other product please contact our sales department at [email protected] or
[email protected].
Although we produce the DMMetering PRO1250 SERIES meter according to IEC
62053-21 and our quality inspection is very accurate there might always be a
possibility that your product shows a fault or failure for which we do apologize.
Under normal conditions your product should give you years of benefit and pleasure.
In case there is a problem with the energy meter you should contact your dealer
immediately. All energy meters are sealed with a special seal. Once this seal is
broken there is no possibility to claim for warranty. Therefore NEVER open an
energy meter or break the seal of the energy meter. The warranty time is 5 years,
after production, and only valid for construction faults.
