This device is marked with the international caution symbol. It is important to read the

Recommended Operation section of this manual before using this device as it contains important

information related to product safety.

General Precautions

♦ All insulation of leads connected to output terminals should have at least a 300V rating.

♦ Do not use clip leads in the connections used in arrangements employing the VF-500 linear

amplifier. They are very dangerous for high-voltage work.

♦ Do not place objects on top of or close beside the amplifier during operation. Adequate

airflow around the unit is needed to allow heat to dissipate.

Acceptable Load Types

♦ This amplifier is designed to drive capacitive loads only. Do not use this amplifier to drive

resistive loads. The amplifier will only work properly when a capacitive load is connected to

the output.

♦ Never connect an inductive or a resistive load to the unit. This would cause a short-lived

high-current pulse at the output and would damage the amplifier unit.

Short Circuit Damage

♦ Although the VF-500 is protected against a short circuit on the output, it is recommended that

a short circuit condition be avoided.

♦ Never connect an "earth ground" lead (e.g., an oscilloscope ground lead) to the center pin of

the SMA output terminal. This causes a short-lived high-current pulse and subsequent

damage to the unit.

♦ If the user desires to observe or audit the output signal of the amplifier using a voltage meter

or an oscilloscope, the user must ensure that the meter or oscilloscope has an input

impedance of at least 1 MOhm. Smaller input impedances could damage the amplifier.
