Manual testing of hospital and care beds (UNIMET
®
300ST)
The manual test is basically carried out the same way. However, manual measurements where the
bed is in operation (e.g. leakage currents) and the measuring of the insulation resistance are
different. These measurements are carried out as follows:

With leakage currents, the supply voltage to the bed is uninterrupted; with the insulation meas-
urement, the measuring voltage is uninterrupted.

With the measurement where the bed is supplied with voltage, the head and footboard are
operated along with other electrically actuated adjustment devices. The adjustment devices
are operated until their limit switch responds.

Various accessible metal parts of the bed can be scanned with the test probe.

The measurement is repeated until the ENTER button " " is pressed.
In this way, changes in the measured values caused by operating the adjustment devices on the bed
are reliably detected.
The display alternates as follows:
