3-11. Remove the Instrument Case

Use the following procedure to remove the instrument case.

1.Make sure the instrument is powered off and disconnected from the power source (ac or dc).

2.Remove the screw from the bottom of the case, and remove the two screws from the rear bezel as shown in Figure 3-2. While holding the front panel, slide the case and rear bezel off the chassis. (At this point, the rear bezel is not secured to the case.)

3-12. Remove Handle and Mounting Brackets

Refer to Figure 3-3 during this procedure. Pull each handle pivot out slightly at the handle mounting brackets, then rotate the handle up over the display. With the handle pointing straight up, pull out and disengage one pivot at a time.

Use a Phillips screwdriver to remove the two handle mounting brackets. Note that these brackets must be reinstalled in their original positions. Therefore, the inside of each bracket is labeled (R for right, L for left) as viewed from the front of the instrument.

3-13. Remove the Front Panel Assembly

Note

Parts referenced by letter (e.g., A) are shown in Figure 3-4 (2620A or 2625A) or Figure 3-5 (2635A).

Use the following procedure to remove the Front Panel Assembly (E):

1.Remove the leads connected to the two input terminals. Using needle nose pliers, pull and disconnect the wires at the rear of the VΩ and COM input terminals.

2.Using needle nose pliers, disconnect the display ribbon cable (G) on the Main PCA

(H) by alternately pulling up on each end of its connector. Avoid breaking the alignment tabs on the Main PCA side of this connection.

3.Remove the Front Panel Assembly by releasing the four snap retainers (I) securing it to the chassis. Using needle nose pliers, disconnect the display ribbon cable (G) on the Display PCA (K) by alternately pulling up on each end of its connector. Avoid breaking the alignment tabs on the Display PCA side of this connection. The ribbon cable (G) may be left attached to the chassis.

4.The green power switch activator rod (J) extending from the power switch on the Main PCA through the Front Panel Assembly can now be removed. Squeeze the end of the rod at the power switch and lift up; the bar disengages smoothly from the switch.

3-14. Remove the Display PCA

Two movable tabs hold the Display PCA (K) in place on the back of the Front Panel Assembly. Release one tab at a time. Then, while prying slightly at the top of the Display PCA, lift the pca out of its securing slots. Parts referenced by letter (e.g., A) are shown in Figure 3-4 (2620A or 2625A) or Figure 3-5 (2635A).
