Temperature - Type K TC

Temperature - Type K TC	Measuring range dependent on probe type used
Temperature - Type K TC	Accuracy ±2 °F (Remaining Range) * / ±1 °C (Remaining Range) * ±0.7 °F (-148° to 392 °F) * / ±0.4 °C (-100 to +200 °C) *
*Accuracy information applies only to instrument without probes connected

Differential pressure (internal sensor)

Differential pressure (internal sensor)	Measuring range 0 to +80 InH₂O / 0 to +200 hPa
	Accuracy ±1 InH₂O or ±1 % of full-scale value (16 to +80 InH₂O) / ±2 hPa or ±1 % of fsv (41 to +200 hPa) ±1.5 % of mv (+1.2 to +16 InH₂O) / ±1.5 % of mv (+3.1 to +40 hPa) ±0.01 InH₂O (0 to +1 InH₂O) / ±0.03 hPa (0 to +3 hPa)
	Resolution 0.01 InH₂O / 0.01 hPa

Pressure measurement (external probe)

Pressure measurement (external probe)	Measuring range 0 to +363 psi / 0 to +25 bar
	Accuracy ±0.6 % of full-scale value (>+145 to +363 psi) / ±0.6 % of fsv (>+10 to +25 bar) ±0.6 % of full-scale value (0 to +363 psi) / ±0.6 % of fsv (0 to +25 bar)
	Resolution 10 InH₂O / 10 hPa
