Cleaning

This i nstrum ent shoul d be clea ned as often as operati ng co nditio ns requi re. Loose dust accum ulated on the outside of the instru ment can be removed with α soft clot h or small br us h. Remove dirt that remai ns with α soft clot h da mpened i n α mil d deterge nt and water sol utio n . Do not use abrasive cleaners.

The best way to clea n the interior is to blow off the accum ulated d ust wit h dry, low-velocity ai r (approximate- Ιγ 5 I b/ίη 2 ) or use α soft br ush or cloth dampened with α mild detergent and w ater solution.

Circuit boards an d compon en ts must be dry b efore applying pow er.

Obtaining Replacement Parts

Elect rical and mec hanical parts can be o btained t hrough your local Tektroni x Field Office or represen- tati ve.
