PROTECTING YOUR INSTRUMENT
TURN OFF INSTRUMENT WHEN NOT IN USE
The lifetime of the switching elements in the pulse generator module is proportional to
the running time of the instrument. For this reason the prime power to the instrument
should be turned off when the instrument is not in use. In the case of failure, the
switching elements are easily replaced following the procedure described in a following
section.
DO NOT EXCEED 1 kHz
The output stage may be damaged if triggered by an external signal at a pulse
repetition frequency greater than 1 kHz.
REDUCE FREQUENCY AND PULSE WIDTH
In general, the lifetime of the output stage will be extended if the pulse repetition
frequency and the pulse width are kept as low as possible.
USE A HIGH-IMPEDANCE LOAD
The load impedance must be 10 kΩ or higher. The output stage may be damaged if
lower impedances are used.
