the unit, or at 6 month intervals.
After 220 operations the message ‘CAL. DUE: 30’ will be
displayed whenever the instrument is switched on. This
indicates that calibration will be due after the unit has been
switched on 30 more times. This figure will decrease every
time the unit is switched on. After 250 operations, the
message ‘CAL. OVERDUE: 01’ will be displayed whenever
