4-13. Setting the PROTECT/UNPROTECT Switch to PROTECT

The effects of ELECTROSTATIC DISCHARGE can damage electronic compo- nents. Use grounded wrist straps and mats when you are performing any kind of service on this module.

The PROTECT/UNPROTECT switch must be set to PROTECT after calibration is finished. Set the switch to PROTECT as follows:

1.Remove power from the instrument. Pull the modules located above the oscilloscope halfway out, then remove the filler panels and cards located above the oscilloscope. See figure 4-6 for the removal sequence.

Figure 4-6. Endplate Overlap - Top Sequence

2.Remove the oscilloscope module and set the PROTECT/UNPROTECT switch to the PROTECT position. See Figure 4-2 to locate this switch.

3.Repeat step 2 for each module calibrated.

4.Reinstall the modules and filler panels in reverse order of steps 1 and 2.

4-14. Sealing the Mainframe

After calibration has been completed, the mainframe should be sealed to protect the integrity of the system. Place a seal on the equipment such that the seal touches both the top-most module (or filler panel) and the mainframe.
