Note: Calibration interval is calculated from either In-Service Date or last Calibration date (see SHOW
INFO menu) depending on which is more recent date. When clock Date is greater than In-
Service or Last Calibration date, plus Cal Interval, "CAL NEEDED" message will be displayed on
power up and after a re-zero. Pressing ENTER
torque while "CAL NEEDED" message is displayed will immediately display torque or angle
measurement and return to target menu when released.
Note: As an alternative to calibration interval, a Calibration Cycle Counter is provided in Calibration
menu (Contact your local Snap-on Repair Center regarding Calibration menu).
