Place the WTT-110 Wire Terminal Tester on a level and stable work area where the
user can perform the testing in a comfortable manner. The surface should be clean and
grease-free, so that the instrument does not slip.
Make sure that there is no residue from the pack-
aging materials stuck under and around any of the
operating components especially in the recessed
area around the rotating terminal fixture (see photo)
and under the lever arm base plate, etc.Use of
compressed air to clear any debris from these
areas is recommended.
Please note that the instrument weighs approximately 30 pounds (14 kg), so please use
necessary precautions when lifting and moving. We suggest that the location is in close
proximity to an AC-Power outlet.
Locate the lever and screw it in to the
threaded hole in the rotating wire clamp
fixture, as shown in the photo. Turn the
lever in a clockwise direction to screw-in.
Continue until it is “hand-tight.” DO NOT
OVERTIGHTEN.

(
REQUIRED BEFORE FIRST USE
)
For safety reasons, the WTT-110 is supplied with the batteries fully discharged.
To obtain maximum battery life we recommend that you charge the internal NiCd
battery for approximately 18 hours before first using this instrument the first time.
Select the appropriate plug adapter for the outlet type and country of use. Plug the
charger into an AC-outlet and plug the other end into the receptacle on the left side of
the WTT-110. Charge the batteries.
Note:
The BAT indicator is shown on the display when the batteries are being charged
and turns off when the batteries are fully charged. When the batteries are nearly
discharged, the "LO BAT" indicatory will blink on and off.

PERATION
The WTT-110 can be operated using the AC-Adapter/Charger. The batteries are being
recharged while plugged into the AC power source. Total battery recharge time will be
significantly longer then if recharged while turned off.
