724/725/726
Calibration Manual

Specifications

Performance and accuracy are specified for one year after calibration, at operating
temperatures of +18 °C to +28 °C (64 °F to 82 °F), in relative humidity to 90 %, after a 5
minute warm up period.
A "count" is the amount by which the least significant digit can vary.
