Options List
1. Disconnect the input power to the Model 1088B.
2. Using a T-25 torx driver (or a flat-blade screwdriver), remove the four screws securing the
top cover of the instrument, and remove the cover.
3. Locate the Option 19 terminal strip assembly. Using a T-10 torx driver, remove the two
screws holding the assembly to the main chassis.
4. Remove the three-wire connector from the header on the Option 19 circuit board. (Note:
It will be necessary to perform step 3 prior to removing the connector, in order to allow
clearance.)
5. Remove the entire Option 19 fault relay assembly from the Model 1088B.
6. The location for the optional resistor is shown on the circuit board as R1. Directly below this
lettering on the board is a via (a plated-through hole connecting the two board layers). Using
a number 60 (.040) or larger drill bit, carefully enlarge the via to remove the plating, which
will break the connection between the two layers. CAUTION: The via is the middle of three
holes; be careful not to drill out either of the two outside holes.
7. Install a 100 ohm, 0.5 watt resistor (or the value of your choice) between the two outside
holes, and solder into place.
8. Re-attach the connector to the Option 19 circuit board, using care to insure the proper
polarity.
9. Install the Option 19 assembly back into the Model 1088B, and secure in place with the two
mounting screws.
10. Replace the instrument top cover, and secure with the four T-25 screws.
