Components and Controls:
(A) Socket Open/Close Handle
oThis handle controls the opening and closing of the jaws located
inside of the meter socket. The jaws must be closed and the WECO-
300 must detect a meter in the socket before voltage and current can
be applied. You can lift the handle and reposition the operating
position to your preference. By depressing the handle top button the
handle can be oriented to an alternative position.
(B) Meter Detected LED
oThis LED will illuminate when the WECO-300 has detected a meter
present in the Meter Socket. The WECO-300 must be turned on, one
black paddle on the top and one black paddle on the bottom must be
engaged, and the Socket Open/Close Handle must be in the Closed
position for the WECO-300 to illuminate this LED.

10
03-18 WECO-300 Operations Manual RR944058.2
Radian Research, Inc.
(C) Voltage ON LED and Switch
oThe Voltage ON switch controls the application of voltage to the
socket. Voltage will only be applied when the WECO-300 detects a
meter present in the socket. The Voltage ON LED will illuminate
when voltage is applied to the socket.
(D) Current ON LED and Switch
oThe Current ON switch controls the application of current to the
socket. Current will only be applied when the WECO-300 detects a
meter present in the socket. The Current ON LED will illuminate
when current is applied to the socket. The Current On switch is only
active when the Voltage On switch is enabled.
(E) Disconnect Closed Indicator LEDs
oThe Disconnect Closed LEDs will illuminate when the WECO-300
detects that the meter disconnects are closed.
Note: LEDs will remain illuminated if the Current Switch is ON. For
the LEDs to go out, the disconnect must be open AND the current
switched off.
(F) Forward/Reverse Switch
oThe Forward/Reverse Switch controls the desired energy flow of the
WECO-300. Forward is for Delivered Energy and Reverse is for
Received Energy.
(G) 30 Amps/3 Amps Switch
oThe 30 Amps/3 Amps switch lets the user select the amperes that will
be applied to the Meter Socket.
(H) Meter Socket
oThe Meter Socket holds the meter that the user is testing, as well as
applies voltage and current to the meter that is present in the socket.
(I) Power LED
oThe Power LED illuminates when the WECO-300 is receiving power
and the unit is turned on.
(J) Power Switch
oThe Power Switch on the WECO-300 turns the unit on and off. The
Power Switch is also a circuit breaker to protect the entire unit.

11
03-18 WECO-300 Operations Manual RR944058.2
Radian Research, Inc.
(K) Voltage Breaker
oThe Voltage Breaker is a “pop-out” style breaker and protects against
a defective meter. If this breaker is tripped, the user can remove the
meter and depress on the voltage breaker button to reset the breaker.

Meter Socket Diagram
The WECO-300 Desktop Meter Test Station requires little maintenance. However,
certain maintenance tasks should be performed to maintain the life, longevity and
your unit operating efficiency.
Before each use:
‐Inspect the unit and power cable for any damage.
Monthly or after every 500 meters:
‐Clean the surface area of the Meter Socket using a soft brush or a paint
brush. Remove all dust, dirt and grime.
‐Check the surface of the shield. If it contains oil or grease, use a soft cloth
moistened with isopropyl or denatured alcohol to remove any contaminates.
Isopropyl alcohol can be purchased at any drugstore or chain store and is
preferred because it will thoroughly clean and degrease the surface without

15
03-18 WECO-300 Operations Manual RR944058.2
Radian Research, Inc.
leaving a residue. Do not saturate the cloth, use only enough alcohol to
remove the grease and not drip alcohol into the test board or the socket jaws.
‐Inspect the Meter Socket surface for damage such as cracks or punctures.
Surface damage is rare.
‐Clean the contact surfaces of the jaws in the Meter Socket using a soft cloth
wrapped around a tongue depressor or Popsicle stick. Lightly moisten the
cloth with isopropyl or denatured alcohol. Do not saturate the cloth, use only
enough alcohol to remove contaminates. Be careful not to remove the
lubricant at the pivot pin. Ample lubrication is applied at the factory to last
the life of the socket. Excessive alcohol will collect at the pivot pin and
degrade or remove the lubricant causing the jaws to wear prematurely.
‐Inspect the jaws in the Meter Socket. Look for contaminants that were not
removed during cleaning. Examine the jaw for damage from debris that may
have been attached to the meter spade(s). Be sure the silver surface of the
contacts is not scratched or pitted. Look for signs of wear.
‐The voltage pins of the socket require minimal maintenance. Clean the pins
using a soft cloth moistened with isopropyl or denatured alcohol. Apply light
pressure while rubbing the contact surface of each pin in a circular motion.
‐Inspect each pin. Look for signs of wear along the shaft. Look for deep
scratches on the contact surface of each pin. Also check for contaminates that
may not have been removed during cleaning. Fully depress each pin and
release to ensure the spring returns the contact to the original position.
