Installation / Setup
The normal operating position for the ESV test receiver is horizontal, which is the position in which it is tested and calibrated. When used on a bench, the carrying handle should be swung fully down to rest the unit on it. For portable use in the field, the receiver can be operated in a vertical position, and a protective cover is recommended for the rear. In vertical position, meter readings may vary by approximately 2% compared to horizontal use.
The maximum allowable operating temperature is +45°C. When operating from batteries, self-heating is negligible. However, during AC supply operation with battery charging, significant heat can develop at the rear, so a 10 cm clearance from surrounding objects is advised to prevent heat build-up. Direct sunlight protection is generally not needed unless the case feels too hot to the touch.
Operation
The manual provides detailed instructions for setting up and operating the ESV test receiver. The normal operating position is horizontal, which is also the position in which the receiver is tested and calibrated. For bench use, the carrying handle should be swung fully down to rest the unit on it. In portable use, the receiver can be operated in a vertical position, though readings may vary slightly compared to horizontal use. The maximum allowable operating temperature is +45°C. When operating on AC supply, it is advisable to maintain a 10 cm distance from surrounding objects to prevent heat buildup.
