3.3.2.4. NOTE: The colon flashes at the rate of one cycle per second regardless
of the selected mode.
3.3.3. ACCURACY AND STABILITY:
3.3.3.1. ±0.01%
3.3.4. POWER FAILURE PROTECTION:
3.3.4.1. An internal rechargeable battery maintains (for several hours) the clock
and other vital circuits for a dependable resumption of operation after a
power failure.
3.3.4.2. The colon will be lit in case of a power failure.
3.3.4.3. NOTE: Do not operate the Charger-Analyzer without this battery or
with a battery in bad condition. Replace only with the same type, 7 or 8
cells (8.4V or 9.6V), rechargeable).
3.3.5. TIME LIMITS:
3.3.5.1. 0 to 9 in Main
3.3.5.2. 0 to 79 in Total
3.3.5.3. NOTE: The time limit in Total is dependent on the type of Timer.
Newer instruments, characterized by a Timer Speed Switch mounted
on the Front Panel have a limit of 79 (hours or minutes) while older
units have a limit of 60.
3.4 LINE INPUT VOLTAGE:
3.4.1. 115V(*), 208V, 230V, 245V
Note: For proper operation of this instrument, power line voltages must be
within ±10% of the nominal.
3.4.2. The instrument is normally wired for 230V operation.
3.4.3. A terminal block at the transformer inputs allows field re-wiring for 245V, 208V
or 115V operation. See figs 3, 4 and 5 .
3.4.4. For operation at line voltages in excess of 220V at 50Hz, it is required that the
245V tap be used.
3.4.5. NOTE (*): Operation at 115V is not recommended at battery charging currents
above 15A due to the increased line current.
