Only use this instrument in the manufacture specified 
temperature range. 

2.

 

The handle of this instrument can become hot when it is used 
to measure high temperatures for extended periods of time. 

3.

 

DO NOT submerge SPRT handle when taking measurement. 

4.

 

DO NOT use this instrument to measure the temperature of 
any hazardous live component. 

5.

 

Follow all other safety guidelines listed in this user’s guide. 
 

 

Cautions: 

Follow these guidelines to avoid possible damage to 

the instrument:

 

1.

 

Avoid mechanical shocks. DO NOT drop or slam the probe in 
any way. This will cause damage to the probe internally and 
affect its calibration and accuracy. 

2.

 

Read Section entitled “Care and Handling Guidelines” before

can damage the SPRT and void the warranty. 

3.

 

Keep the shipping container in case it is necessary to ship the 
PRT. Incorrect packaging of the SPRT for shipment can cause 
irreparable damage. 

4.

 

Calibration equipment should only be used by trained
