4 Care and Handling Guidelines

1. DO NOT subject the SPRT to any physical shocks and

vibrations.

a. When not using the SPRT, keep it in a pla

ce that’s not

prone to drop, slam, bang, vibration or other strong
physical contacts. Use a protective box or a carrying
case whenever possible.

b. When shipping the SPRT, use protective box and other

protective packaging materials to minimize mechanical
shocks as much as possible.

c. When using dry blocks, make sure the well diameter is

appropriate to allow the SPRT move up and down
smoothly.

2. DO NOT subject the SPRT to any contaminations.

a. Keep the SPRT as clean as possible. Avoid

contaminations as much as possible.

3. DO NOT over heat.

a. Do not use SPRT above the manufacture specified

temperature range.

b. Do not expose the SPRT handle and lead wires to

extreme temperatures.
