Thermal Zero Shift (TZS) is the maximum amount the output or reading at the null measurement point might deviate over the compensated temperature range. This error is typically expressed as a percentage of full scale output or reading. It can also be expressed as percentage of full scale per degC, degF or K e.g. ±0.02%FS/DegC.
