Operating requirements
Use the instrument within the required operating temperature, power, altitude, and signal input voltage ranges to provide the most accurate
measurements and safe instrument operation.
Table 1: Environment requirements
Characteristic Description
Operating temperature 0 °C to +50 °C (+32 °F to +122 °F)
For proper cooling, keep the sides and rear of the instrument clear of obstructions for 2 inches (51 mm).
Operating humidity 5% to 90% relative humidity (% RH) up to +40 °C (+104 °F), non-condensing.
5% to 55% RH above +40 °C up to +50 °C (+104 °F to +122 °F), non-condensing.
5% to 90% RH at temperatures up to +60°C (+140°F), non-condensing, and as limited by a maximum
wet-bulb temperature of +39°C (+102°F).
Operating altitude Up to 3000 meters (9842 feet)
