• Use a damp cloth to regularly clean the outside of the meter.Do not
use abrasives or chemical solvents. Dirty or damp input jack can
adversely affect readings.
• To clean input jacks, follow the following steps:
1.Turn off the instrument and remove the test leads.
2.Clear any dirt or other particles on the input jacks.
3.Use a cotton ball/swab with a lubricant (i.e. WD-40) to clean off the
contacts of the input jacks.
4.Use a separate cotton ball/swab for each jack to prevent
cross-contamination.
