To return to normal mode press the TURN ON button shortly in either unit. Both units will
resume normal operation automatically. After normal operation is resumed the ON led will light
continuously.
FIBER OPTIC CONNECTIONS
The probe head unit and the receiver are connected with two fiber optic cables. These are not
the same standard fiber cables as those found in a house installation. Although these cables
have a 4 layer protection, be mindful that they are not as resilient as copper cables so do not
bend them sharply, avoid putting tension on cables and do not pull them, especially when
kinks or knots are present.
Also do not remove or bend the protective fiber optic cable boots since these protect the
connectors from dust and maintain the necessary alignment for proper accuracy.
CALIBRATION
Calibration is needed to adjust the analog parameters of the fiber optic link and correct for
offsets and temperature drifts in each unit. Every time the CAL button is pressed both probe
head and receiver run self-test prior to calibration. It is not necessary to disconnect the probe
from the measured system in order to execute the calibration.
A short blink from the CAL led indicates that calibration is required. To execute calibration, first
turn on both units and then shortly press the CAL button. The CAL led will turn on. If for some
reason both units cannot communicate or the scope is not 50 terminated, the CAL led will
