The temperature range may be limited by the reference probe connected to the readout. The Built-
In Reference Accuracy does not include the sensor probe accuracy. It does not include the probe
uncertainty or probe characterization errors.
Measurement accuracy specifications apply within the operating range and assume 4-wires for PRTs.
With 3-wire RTDs add 0.05 ohms to the measurement accuracy plus the maximum possible difference
between the resistances of the lead wires.

Environmental Conditions

Although the instrument has been designed for optimum durability and trouble-free operation,
it must be handled with care. The instrument should not be operated in an excessively dusty or
dirty environment. Maintenance and cleaning recommendations can be found in the Mainte-
nance section. The instrument operates safely under the following environmental conditions:
ambient temperature range: 0-50°C (32-122°F)
ambient relative humidity: 0 % to 90 % (non-condensing)
mains voltage: within ±10% of nominal
vibrations in the calibration environment should be minimized
altitude: less than 2,000 meters
indoor use only
