1: Meter Overview
1.1: The Shark® 250 High Accuracy Revenue Meter
The Shark® 250 is a multifunction, data-
logging revenue meter for both critical
meter applications and basic commercial/
industrial metering applications. The
Shark® 250 meter is a full four quadrant,
bidirectional revenue meter that can also
be used for inter-tie metering. Its 0.2%
metrology accuracy meets all the accu-
racy requirements of ANSI C12.20 Class
0.2% and IEC 62053-22 CL 0.2S. The
meter has advanced revenue metering
features that allow it to be used not only
for measuring basic energy, but also for
providing a full complement of necessary
tools, such as instrument transformer compensation, CT/PT compensation, advanced
test mode, perpetual TOU, and extensive logging for interval energy storage.
There is also a transducer only version of the meter, the Shark® 250T transducer,
which has the same functionality as the meter, except that it doesn’t have the face-
plate or the USB port.

1.1.3: V-SwitchTM Key Technology
The Shark® 250 meter is equipped with V-SwitchTM key technology, a virtual
firmware-based switch that lets you enable meter features through software
communication. V-SwitchTM key technology allows meter upgrades after installation
without removal from service.
** Note that some memory is reserved for internal operations.
*** See the Shark®250 Meter Modbus Protocol Application Guide for instructions on
using Modbus with the meter.

Obtaining a V-SwitchTM Key:
Contact EIG’s inside sales staff at [e-mail] or by calling [phone]
(USA) and provide the following information:
1. Serial number(s) of the meter(s) you are upgrading. Use the number(s), with lead-
ing zeros, shown in the Communicator EXTTM Device Status screen (from the
Communicator EXTTM Main screen, click Tools>Device Status).
2. Desired V-SwitchTM key.
3. Credit card or Purchase Order number. EIG will issue you the V-SwitchTM key.
Enabling the V-SwitchTM Key:
1. Open Communicator EXTTM software.
2. Power up your meter.
3. Connect to the Shark® 250 meter through Communicator EXTTM software.
4. Download all meter logs and then reset them - see chapters 16 and 20 in the
Communicator EXTTM 4.0 and MeterManager EXT Software User Manual for instruc-
tions on doing this; you can access the manual by clicking Help>Contents from the
Menu Bar at the top of the software’s Main screen.
