BRIEF CHECKING PROCEDURE
General
The purpose of this operation is to check the functions of the PM 5191 with the least amount of time
and effort.
It is assumed that the operator is familiar with the PM 5191 and its characteristics. If the test is carried
out shortly after being switched on, the individual testing steps could lead to incorrect results owing to
the warming-up time being inadequate.
WARNING: Before switching on ensure that the equipment has been put into operation in accord-
ance with chapter 2.
Operations Test
Immediately upon being switched on, a self-test is carried out. The instrument then automatically
returns to its basic status (see chapter 3.3.). The equipment's last operational status prior to being
switched off is displayed. Using key |ENTER| execute this setting.
If you prefer a different operation mode, then just input new parameters.
example: wave form sine
frequency 150 Hz

ievei: amplitude (Vpp) iv
DC offset (Vdc) OV

— connect the oscilloscope to socket OUTPUT (see chapter 3.5.2.1.) (Zo = 50 ohm) and check the
signal. If it is correct, the operations test is finished. If not, repeat the procedure with other settings.
