4.0 Operation
Before operating any components, follow the
safety information in the ETS-Lindgren
Product Information Bulletin included with your
shipment.
Do not attempt to operate a microwave oven
with:
 Any object caught in the door
 A door that does not close properly
 A damaged door hinge, latch or
sealing surface
Do not use the HI-1801 without the spacer cone
in position.
The areas where leakage is likely to occur are around the door seal, the window,
and at ventilation louvers or vents. A damaged or improperly installed magnetron
mounting gasket may cause leakage in the control panel area of the oven.
Accuracy
The accuracy of the ETS-Lindgren Model HI-1801 Microwave Survey Meter is
within ± 1 db (+25%, -20%) when used according to these instructions:
1. Always use a clean spacer cover. Accuracy will be affected by wear of the
cover and by dirt and metallic particles which may become imbedded in the
EPS (expanded polystyrene) foam. If the cover is damaged, contact
Customer Service for a replacement.
2. Hold the instrument case at approximately 45º. The balance of the meter
movement causes the needle to move slightly when held horizontally (flat)
or vertically (upright). The meter is calibrated while at an angle of 45º and if
it is used at that angle, no additional error will be introduced.
