Note: When the Interface Box is connected to the 3650Ex instrument, this also acts as a power supply to the
instrument and disconnects the internal battery power source.
Connect the power cable supplied with the instrument to the socket at the rear of the interface box for
alternative current (AC) power connection. To switch the instrument on and off, press the rocker
switch (right in the diagram) - " I " for On and " O " for Off. Refer to
If the device function does not start when the device is set to on, disconnect the power cable from the
socket and do a test. If the cable operates correctly, open the fuse box with a flathead screwdriver.
Refer to
. Do a test of the electrical continuity of the two fuses with an ohmmeter. If one fuse
or two fuses are blown, replace the blown fuse(s):
• T0.25AL 250 V, 5 x 20 mm-Replace with 29122.A 120 VAC
• T0.1AL 250 V, 5 x 20 mm-Replace with 29122.B 230 VAC
If the problem continues, contact technical support.
