Handling & Maintenance
1. Store the PRF-912B in a clean, dry environment with both BNC and Probe covers
installed for environmental and mechanical protection.
2. Periodically, remove all spring-loaded test pins. Clean the spring-loaded test probes
and Teflon mounting disk with a solution of laboratory grade isopropyl alcohol and a
lint-less cloth, or laboratory quality swab. Allow components to dry thoroughly be
fore re-assembling.
a. Remove each test probe individually by grasping it firmly
then pulling it straight out of its socket.
b. Inspect each probe for damage, then clean with the
alcohol solution. If a probe is damaged, i.e., bent, does
not compress smoothly, or has deep surface scratches,
replace it with a new probe of the same size and
characteristics. (Contact Prostat Corporation, Customer
Service for spare replacement probes.)
c. Clean and dry the Teflon mounting disk twice to insure
cleanliness
d. Carefully re-install the spring-loaded test probes, and
fully re-seat them in their sockets
