Adjusting Cal HL and

The Cal HL level shown on the CONTRA SPL CAL and IPSI SPL CAL screens

Target SPL levels can be adjusted in 5.0dB increments to accommodate background noise levels in

the calibration environment. As the Cal HL level is adjusted up or down, the TARG

SPL level automatically tracks to eliminate the need for separate transducer target

SPL adjustments.

80 dB HL changed to 90 dB HL

The TARG SPL level shown on the CONTRA SPL CAL and IPSI SPL CAL

screens can only be adjusted when a custom transducer has been specified by set-

ting switch #2 of the calibration options DIP switch to the ON position. The appro-

priate target SPL can be incremented up or down in 0.5dB increments for each

probe tone frequency.

NOTE

Target SPL values must be within 10dB of the GSI default values.
