OPERATING INSTRUCTIONS – CATALOG NO. 2100-I-E-V Desktop Meter Station

Description

The TESCO Catalog 2100 Desktop Meter Station is powered by a single phase 120VAC 5A
source. The 2100 is a multi-form meter testing device. Its small footprint allows use in an office or
shop environment. Depending on the options selected a load current can be applied to the meters
"A" phase stator. The 2100 can be used for qualification testing of solid state and mechanical
meters (when the tilt version is chosen), verifying meter functions, and program updates. The unit
is protected by a 2 amp circuit breaker.

Meter Potential Voltage

The Voltage selector switch sets the meter potential voltage. The settings are 120V, 208V, 240V,
277V, and 480V. Potential voltage is wired parallel to all meter coils. Note that some newer meters
have an auto ranging feature for voltage and will run at wide range of voltages (see manufacturers
specifications). Some legacy meters can only be powered by a specific voltage. The user should
verify all meter documentation and labeling.
When the 2100 is ordered with the 500VA transformer for testing disconnect functions the 2s meter
should only be tested at the 240 volt setting. This will configure the meter with a 3-wire circuit with a
virtual neutral. This will ensure that the meters back voltage detection will not prevent the disconnect
switch from closing.
This 2100 3-wire configuration is also connected for 12S meters when the disconnect option is
specified. The 3-wire circuit is hardwired (switched) to the 12S form. The voltage selector is
disconnected when 12S is set.

Loading Options

Internal 0.5 amp load:

A 0.5 amp phantom load will be applied to the A stator coil of the meter. Once the meter is
installed and the POWER pushbutton is depressed the load will be applied to the meter.

Load Receptacle:

A 120VAC, 15 amps NEMA 5-15 receptacle is mounted to the front of the unit. Line voltage is
connected to the receptacle through the meter "A" leg. Once the meter is installed and the
POWER pushbutton is depressed the load connected to the receptacle will be powered.
When this option is specified an additional 15 amp fuse is added to the 2100 front panel (to the
left of the receptacle). This fuse protects the unit and will open should any device requiring
greater than 15 amps, or that is faulty, be plugged into the receptacle.

Binding Posts:

Two fifty amp binding posts are mounted to the front of the unit, labeled BP1 and BP2. Binding
post (BP1) is connected to the "A" line stab of the meter and binding post (BP2) is connected to
