operation using the
Enter
key. The captured vale is then shown in the upper left corner of the
display together with its sequential number. If multiple values are stored, the list can be
browsed using the arrow keys. A new measured value is always appended to the end of the list.
The shown value can be removed using the
Delete
key. If this key is held down, multiple
values are deleted until the key is released again. After ten deleted values the deletion is
processed faster.

Switching between Battery Power and USB Power
Important!
The FH 52 should always be switched off before an USB power supply (AC
adapter) is connected or removed.
If a USB power supply (AC adapter) is connected while the FH 52 is operated from batteries
the FH 52 might enter standby mode and not recover from this mode again. If this should
happen, you must remove the USB power supply again. If the FH 52 does not resume operation
in battery mode immediately, wait approximately 30 seconds and try to switch it on in battery
mode again. Then switch it off and connect the USB power supply.
If a USB power supply is removed while the FH 52 is on, the FH 52 will normally continue
operation on batteries. On weak batteries it might happen that the FH 52 restarts or
extinguishes.

Standby Mode
If the FH 52 is connected to a PC and the PC enters the standby or energy saving mode, the
FH 52 will also go into standby mode. In this case the display shows “
Entering Standby
” for a
short time. Modified settings and saved measuring data are copied from the volatile to the non-
volatile memory. Then the display backlight is switched off and the device is set to standby.
The display remains empty. The device is not fully switched off. It only stays in a state of low
energy consumption.
When the PC is wakened up from standby, the FH 52 will also continue operation. The display
shows shortly “
Resuming from standby
” and thereafter the device returns into measurement
operation.
During standby the FH 52 cannot be switched on or off from the keypad. However, it switches
to active battery operation if the USB cable is removed.
3.6
Battery State Indicator
The battery state indicator in the upper right corner of the display is only visible if the FH 52 is
powered from the battery. It is deactivated if the FH 52 is powered from the USB socket.
You can estimate the remaining battery capacity from the battery state indicator. The display
changes from
for a full battery to
if the battery is too weak to ensure full measuring
accuracy.
