Led Backlight Display Operation; Ventilation; Connecting Test Leads Between The Esu And The Analyzer - Fluke RF303 Operator's Manual

LED Backlight Display Operation

The Analyzer's display lights when you select a load or when a test
measurement is received by the instrument.

Ventilation

The Analyzer requires proper ventilation so that it does not overheat during
operation. Always ensure that the two ventilation ports, located on each side of
the Analyzer, are not blocked during use. Maintain at least four inches (10.2
centimeters) of clear space around each of these ports.
An internal fan located immediately behind the grille on the left side port
supplies forced-air ventilation. Sensors measure the temperature of the load
resistors, and the fan accelerates as the load temperature increases. Fan rotation
is monitored also. If the load temperature is excessive or if the fan is not
functioning, an error condition is indicated on the display, and the audio
transducer emits a beeping sound. The error display codes are:
E 01: Temperature too high.
E 02: Fan not operating.
Permanent damage to the Analyzer can occur if you
continue to apply a high-level ESU signal after the alert
has been activated.
Connecting Test Leads between the ESU and the
Analyzer
A complete set of test leads is supplied with the Analyzer. Use these test leads
to connect the ESU generator output to the Analyzer and to configure the
Analyzer to conduct a specific ESU test. Safe connection to the Analyzer is
facilitated by shrouded safety plugs.
