Electrical Specifications
The Product specifications describe the Absolute Specification of the Product. The Product specifications include stability,
temperature, and humidity; within specified limits, linearity, line and load regulation, and the reference standard
measurement uncertainty. The Product specifications are provided at a 99 % confidence level, k=2.58, normally
distributed, unless otherwise stated.
The relative specifications are provided for enhanced accuracy applications. To calculate an enhanced absolute
specification from the relative specification, it is necessary to combine the uncertainty of your external standards with the
pertinent relative specifications. Specifications are valid after allowing a warm-up period of 30 minutes, or twice the time
the Product has been turned off.
