In
this position the instrument is switched off and the contents of the
memory are erased. However, if rechargeable Nickel Cadmium cells are
being used, they can still be recharged when the switch is in this position.
"On" - Power is on in this position and the battery voltage indicator should
move from the red to the blue region, indicating that the voltage from the
batteries, or from the external power supply where used, is sufficient for
proper, reliable operation.
In
addition a number
of
the indicating light
emitting diodes will come on, corresponding to the switch positions select-.
ed during the previous measurement, and the two displays will begin to
indicate. Warm-up time depends on the mode of operation, 5 s for HAND-
ARM,
