R&S Cable Rider ZPH
Figure 3-2: Battery charging and discharging process
Charging time is about three hours when the R&S Cable Rider ZPH is in inactive
mode (i.e. R&S Cable Rider ZPH is switched off). If the instrument is in active
mode (i.e. R&S Cable Rider ZPH is switched on), the charging time is extended
to about four hours because the charging current is reduced as the power is parti-
ally drained by the usage of the R&S Cable Rider ZPH.
During operation in the field, you can also charge the battery with the car adapter
(R&S HA-Z302, order number 1321.1340.02). You can connect the car adapter to
the DC port. With the car adapter, you are able to charge the R&S Cable Rider
ZPH via the car's cigarette lighter socket. A replacement battery (R&S HA-Z306,
order number 1321.1334.02) with the same capacity and charging time as the
battery included in the standard delivery is also available if necessary.
Battery dispatched during delivery is not fully charged, for battery operation
you have to charge it first.
To charge the battery, connect the charger to AC power adapter included in
the delivery. For more information, see
on page 14.
Using an external battery charger
You can also use an external battery charger (R&S HA-Z303, order number
1321.1328.02) to charge the battery.
To charge the battery externally, put the battery into the external charger and
supply it with power via the AC power adapter.
An amber LED on the charger indicates the charging process. The LED turns to
green when the battery is fully charged. A red LED on the charger indicates that
the battery is not charging or the charging failed.
