5.1.5Battery operation
The R&S ZNH has a smart battery indicator which displays the battery charging
status on the [Power] key as well as the battery icon shown at the top right corner
of the display screen. See Chapter 6.6, "Display overview", on page 26.
The lithium ion battery has a capacity of 6.9Ah / 74Wh (at nominal voltage of
10.80V) and it allows operation at preset condition of up to 4 hours when it is fully
charged.
The actual operation time depends on the current charged status (see Fig-
ure 5-2), the ambient temperature and the operating mode of the R&S ZNH.
For a summary of the LED indication of the [Power] key, see Table 5-1.
The battery charging and discharging process of the battery icon indicated in the
display screen is illustrated below:
Figure 5-2: Battery charging and discharging process
Charging time is about three hours when the R&S ZNH is in inactive mode (i.e.
R&S ZNH is switched off). If the instrument is in active mode (i.e. R&S ZNH is
switched on), the charging time is extended to about five hours because the
charging current is reduced as the power is partially drained by the usage of the
R&S ZNH.
