The calibrate reference bottle may

be used as often as necessary to

assure proper operation of determin-

ing the size of the leak. A leak that

causes an audio pitch about equal to

that produced by the calibrate refer-

ence has a leak rate of approximately

the same size, 0.5 ounce per year of

halogen R134a.

Proper unit response during the

R134a calibration reference test above

verifies proper sensitivity and opera-

tion for all three test positions: small,

medium, or large for either chlorine or

fluorine based refrigerants. Please refer

to the Product Sensitivity Levels chart

on the pocket of the inside lid, or see

this manual’s Specifications section.

The term R12 sensitivity is used to

represent chlorine based refrigerants

such as R12, R22, R123, etc. Use

the medium sensitivity switch position

to locate 0.5 oz/yr or greater leaks

of these type refrigerants. The term

R134a ratings apply to the most difficult

to detect, like fluorine based R134a or

SF6. Use the small sensitivity switch

position to locate 0.5 oz/yr or greater

leaks of these type refrigerants.
