With the Knick Fullcheck
®
menu, a complete device
self-test is performed. The complete measuring cir-
cuitry, measured value processing, memories, dis-
play and keypad are checked and each result is
displayed. The tests run automatically. Only during
keypad testing you have to press the requested
keys. Longer testing periods are indicated by a little
running clock on the right display.
Successful testing is confirmed by OK on the right
display.

Amplifier linearity test: Using an integrated, high-
precision reference, the complete measuring cir-
cuitry from input amplifier to recorder output is
checked. The displayed mV values lie across the
recorder output. The electrode is internally discon-
nected from the amplifier.
