Product Overview and Specifications
Measurement Specifications 1
1-15
Measurement Specifications
Accuracy specifications generally apply with medium and slow sample rates (unless otherwise noted), after a warm-up
time of 1 hour, and within an environment temperature range of 18 °C to 28 °C, and may depend on the channel. The
confidence level for accuracy specifications is 95 % within 1 year of calibration.
Scan rate
Fast ..................................................................... 10 channels per second max (0.1 seconds per channel)
Medium ............................................................... 1 channel per second (1 second per channel)
Slow .................................................................... 4 seconds per channel
Display Resolution ................................................ 4 ½ to 6 ½ digits, depending on function and Sample Rate (see
Measurement Characteristics tables below to find the display
resolution of temperature readings)
PRT/RTD
Temperature Range .............................................. −200 °C to 1200 °C (depending on the sensor)
Resistance Range ................................................. 0 Ω to 4 kΩ
Offset Compensation
0 Ω to 400 Ω, 4-wire........................................ automatic current reversal
400 Ω to 4000 Ω or 3-wire .............................. none
Source Current Reversal Interval (0 Ω to 400 Ω range)
Fast sample rate ............................................. 2 ms
Medium sample rate ....................................... 250 ms
Slow sample rate ............................................ 250 ms
Maximum Lead Resistance (4-wire Ω) ................ 2.5 % of range per lead for 400 Ω and 4 kΩ ranges.
PRT/RTD Resistance Accuracy
Accuracy is given as ± (% of measurement + ohms). Basic accuracy is for 4-wire PRT/RTD using medium or slow sample
rate. When using 3-wire PRT/RTD add 0.013 Ω to the accuracy specification for internal resistance mismatch and voltage
offset if using Channel 1, or add 0.05 Ω if using channels x01 through x20. When using Fast sample rate add the number
given in the table to the accuracy specification. The 4 kΩ range accuracy specification can be decreased by 0.06 Ω if
using Slow sample rate. If the environment temperature is outside the specified range, multiply the temperature coefficient
numbers by the temperature deviation and add to the accuracy specification.
