Introduction
1.1
State-of-the-Art Meter Accuracy Testing in an Affordable Desktop Configuration!
Tired of waiting for access to a production test board? Tired of wasting time going to another
building to use test equipment? Need flexibility, state -of-the-art performance, and ease of use?
If so, then TESCO’s revolutionary 2990 Desktop Meter Test Station (DTS-2990) is the answer to
what you need.
The 2990 revolutionizes meter testing by providing full series parallel meter testing in a small,
budget-friendly desktop package.
A fully ANSI compliant test board, it offers complete testing of all meters under the widest range
of test conditions. It can perform Manual Test, Sequence Testing, PLC Test, and Disconnect Test
for meters with a wide array of forms. It has a database for storing and viewing of the test data.
The new waveform generator has all waveforms called out in ANSI C12.20-2015 (pub. 4/2017).
All common electromechanical and solid-state meters up to 50 amps can be tested with the
2990 using the single voltage and three isolated current sources.
For more than 110 years customers have trusted TESCO for accuracy and reliability. When you
think metering, think TESCO.
DTS- 2990 will be referred as “Instrument” all throughout the operational manual.

1.3
This manual contains information and warnings that must be observed to ensure safe operation
and keep the Instrument in a safe condition. Operation or service in conditions or in a manner
other than specified could compromise safety. For the correct and safe use of this device, it is
essential that both operating and service personnel follow accepted safety procedures in
addition to the safety precautions specified.
In this manual, a WARNING identifies conditions and actions that pose hazard(s) to the user,
while a CAUTION identifies conditions and actions that may damage the Instrument or the test
equipment.
WARNING
To avoid electrical shock, personal injury, or fire hazard:
The device must not be switched ON if it is damaged or suspected to be faulty.
Do not operate the device in wet, condensing, dusty, or explosive gas conditions.
If the equipment is used in a manner not specified in this manual, the protection

2.1 Introduction
This chapter provides instructions for unpacking and installing the Instrument. Read this
chapter before you operate the Instrument. Instructions for cable connections can be found
here.
2.2 Unpacking and Inspection
The Instrument is shipped in a container designed to prevent damage during shipping.
Inspect the Instrument carefully for damage, and immediately report any damage to the
shipper. A packing list is included in the packaging. When you unpack the Instrument, check for
all the standard equipment listed and check the shipping order for any additional items ordered.
Report any shortage to the place of purchase to your distributor or directly to TESCO.
2.3 Set up, Airflow and Cooling Considerations
2.3.1 Setup and Placement
The Instrument is suitable for bench top use if there is enough space to allow proper ventilation.
Please see suggested placement of the setup.
Figure 2.3a Benchtop Suggested Setup
IMPORTANT CONSIDERATIONS:
Since the Instrument is a benchtop
device, the table should:
1- Be stable (should not have
loosely, shaky joints)
2- Have table legs that are
stationary or non-rollers. In
case rollers are present,
ensure that the rollers are
properly locked to avoid
unnecessary movements.

2.3.2 Airflow
Take note of the Instrument’s airflow
as seen in the illustration. This always
for a table top, never on a rack. Please
allow enough airspace at the side with
at least half a meter for an effective
airflow.
CAUTION
Damage caused by overheating may occur if the area around the air intake is restricted, the
intake air is too warm, is interfered, or the air filter becomes clogged.
The inlet and exhaust holes must be clear of obstruction.
The air entering the instrument must be between 5 °C
and 35 °C. Make sure that exhaust from another
instrument is not directed into the fan inlet.
Check and clean the air filter every 30 days or more
frequently if the Instrument is operated in a dusty
environment. Refer to §5.3 for additional info.
2.4 Main Power Supply
The Instrument can be powered by plugging it to a 120V-Single Phase AC line. An AC line power
cord is provided.
1- Power Switch
2- 5A Fuse
3- 3-prong Single Phase
120V AC Line

OPERATIONS MANUAL

WARNING
The Instrument should only be plugged to an AC outlet with a 90 –120V voltage range to avoid
damaging the Instrument.
To avoid electrical shock, personal injury, or fire hazard, connect the factory-supplied three-
conductor-line power cord to a properly grounded power outlet.
During test operation, a two-conductor adapter or extension cord MUST NOT be used. This will break
the protective ground connection and will affect the measurement accuracy of the Instruments.
The power outlets supplying the Instrument system should be controlled by an emergency switch so
that power can be switched off if a hazard arises.
2.5 Utility Meter Insertion/Extraction
The electric meter socket requires zero insertion
force to mount a meter, as well as to dismount
it, upon pressing the meter release button.
WARNING
When mounting a meter, the Instrument must be
switched OFF. In both mounting or dismounting a
meter, the Instrument should not be performing a
test to avoid electrical shock, personal injury, or
fire hazard.
The meter release button* is only operational
when the Instrument is powered up. No meter can
be dismounted when the Instrument is powered
off.
*When the button lights up in glowing red, it can be
pressed to dismount a meter.
INSERTION: To load a meter into the socket, ensure meter is oriented properly. Then insert meter into
socket, keeping the meter weight fully supported. The device will automatically clamp to the jaws of
the meter. When the METER RELEASE indicator turns on, the meter is fully supported. Align optical
pickup to meter prior to testing.
EXTRACTION: To remove the meter from the socket, ensure optical pickup is removed from the face of
the meter. Support the meter shell then press the METER RELEASE button. Once the METER RELEASE
indicator turns off, the meter is safe for removal from the socket.
NOTE: The socket cannot be powered unless a meter is installed, and if the release button is pressed,
power to the socket will be shut off.
