Specifications and Reference Data
PERFORMANCE
SPECIFICATIONS
Accuracy
±0.2% of calibrated span (or, for thermocouple and millivolt inputs, ±0.02
millivolts, whichever is greater). ±0.5% for copper, nickel, and isolated RTD
inputs, 0.1% for differential RTD inputs. Includes combined effects of
transmitter repeatability, hysteresis, linearity (conformity instead of linearity
for thermocouple input), and adjustment resolution. Does not include sensor
error.
Stability
±0.2% of calibrated span for six months.
Ambient Temperature Effect
Errors for 50 °F (28 °C) change in ambient temperature.
RTD Inputs
Zero: ±0.17 °C,
plus
Span: ±0.22%,
plus
Elevation/Suppression: ±0.083% of base temperature in °C.
T/C Inputs (Includes Effect of Cold Junction)
Zero: ±1.38 °C,
plus
Span: ±0.28% of span,
plus
Elevation/Suppression: ±0.11% of base
temperature in °C.
Millivolt Inputs
Zero: ±0.038 mV,
plus
Span: ±0.28% of span,
plus
Elevation/Suppression: ±0.11% of base input in mV.
Input Impedance (Thermocouple and mV Inputs)
More than 1 megohm—burnout resistors disconnected.
Power Supply Effect
±0.005% per volt.
Load Effect
No load effect other than the change in voltage supplied to the transmitter.
Vibration Effect
±0.05% of span per g to 200 Hz in any axis for 3 g’s up to 33 Hz, 2 g’s from 33 to
70 Hz and 1 g from 70 to 200 Hz.
Mounting Position Effect
None.
