Jumper Settings
One jumper (W1) on the IND780 analog scale option board permits the gain of the analog section
to be set to either 2 mV/V or 3 mV/V. The factory default is 3 mV/V, which normally will work well
for both 2 mV/V and 3 mV/V load cells. If 2 mV/V load cells are used, the jumper can be changed
to the 2 mV/V position. Figure 2-40 shows the jumper's location and settings on the board.
The 2 mV/3 mV jumper settings are described in Table 2-6.

Connections
TO AVOID DAMAGE TO THE PCB OR LOAD CELL, REMOVE POWER FROM THE IND780 TERMINAL AND WAIT AT
LEAST 30 SECONDS BEFORE CONNECTING OR DISCONNECTING ANY HARNESS.
When using the IND780 with one or more analog load cells, load cell connections are made to the
connector located on the Analog Load Cell option board. The 7-position connector is visible at top
