4.7. Cooling
The amplifier is fan-cooled so needs an unimpeded airflow from front to rear. A self-resetting
thermal shut-down mechanism will prevent damage through overheating.
Caution:
If used on full power ensure that the equipment is placed in a cool, controlled
environment to prevent activation of the thermal cut-out.
Caution:
The air filter in the front panel [9] should be inspected regularly, and cleaned or
replaced when necessary.
See Air Intake Filter Cleaning and Replacement
.
4.8. Static Field Compensation
The static field is offset by introducing a DC offset into the amplifier input. Lockable controls for
static field offset [5] are available on the amplifier upper front panel to set this compensation.
The static field compensation should be set individually for each axis to obtain a minimum field
in the centre of the coil. This should be measured by a magnetometer placed in the coil centre.
Bartington Defence & Space can provide a suitable magnetometer.
