Weight 2.2lb. (1.0 kg)

Safety OVERVOLTAGE(Installation) CATEGORY II, Pollution Degree 2 per

IEC1010-1

1

Accuracyspecifications apply within the recommended operating temperature range. Accuracy limits are

increasedby a factor of the temperature coefficient outside this range.

2

Short-termaccuracy includes nonlinearity and noise uncertainties. It does not include drift or calibration

uncertainties.

3

Thetemperature range may be limited by the sensor.

4

Temperatureaccuracy is for the 1502A only. It does not include probe uncertainty or probe characteriza-

tionerrors .

3.2 Environmental Conditions

Although the instrumenthas been designed for optimum durability and trou-

ble-freeoperation, it must be handled with care. The instrument should not be

operated inan excessively dusty or dirty environment. Maintenance and clean-

ing recommendationscan be found in the Maintenance Section of this manual.

The instrument operates safely under thefollowing conditions:

•Ambient temperature range: Absolute 0–55°C (32–131°F); [full accuracy

16–30°C (61–86°F)]

•Ambient relative humidity: maximum 80% for temperature < 31°C, de-

creasing linearly to 50% at 40°C

•Pressure: 75kPa–106kPa

•Mains voltage within ±10% of nominal

•Vibrations should be minimized

•Altitude less than 2,000 meters

•Indoor use only
