Identifying a
Secondary Fuse
Problem
To identify a secondary fuse problem in the transmitter:
1. Remove the transmitter from the vicinity of the battery
room.
2. Verify that the transmitter ac line voltage selector is set
for the correct ac line voltage (120 V or 230 V).
The arrow located on the connector panel directly to the
left of the J1 receptacle should point to the arrow on the
fuse carrier that corresponds to the proper voltage.
3. Insert the ac power cord into the J1 ac receptacle. Then
plug the power cord into the 120 V (230V) outlet.
4. Connect the current source leads to the J2 connector on
the transmitter connector panel. Then short (or clamp)
together the red and black clamps of the current source
leads.
5. Press the power switch to the  (ON) position to power on
the transmitter. Press the Current On/Off switch to
energize the current circuit.
The transmitter POWER light and the CURRENT READY
light should illuminate. Also, the digital meter should
indicate current.
If the displayed reading is 0, the
transmitter secondary fuses
may be bad. Refer to "Replacing
Fuses in the BITE 2 Transmitter"
on page 82, or "Replacing Fuses
in the BITE 2P Transmitter" on
page 85, as appropriate.
6. Observe the AC source current reading on analog or
digital meter. Current reading should be about 10 amps
for 60 Hz or about 8 amps for 50 Hz.
