• Periodically check the instrument’s sensitivity by exposing it to a source
of refrigerant gas. DO NOT check sensitivity by cracking open a bottle
of refrigerant or Schrader valve and exposing the sensor to a stream
of pure refrigerant. This will severely reduce sensor life or damage the
sensor.
• Keep the instrument case and probe clean by wiping them with a shop
towel. If necessary, moisten the towel with a mild detergent solution.
Avoid using any type of solvents that may either attack the instrument’s
ABS plastic case, or leave behind a hydrocarbon residue that may de sen -
