Temperature unit °C or °F
Operation
On the device
With the rotary encoder beneath the sealing screw with combination tool or screwdriver
0.5 × 3 mm or Allen key with width across flats SW 2
With PC Via the setup program with PC interface
Measuring input (sensor) 1× Pt1000 temperature sensor, 4-wire circuit
Measuring range Basic type 902940/10: -50 to +150 °C
Basic type 902940/30: -50 to +260 °C
Basic type 902940/50: -50 to +500 °C
Limit deviations 0.15 + 0.002 × |t| a , class A (standard)
0.10 + 0.0017 × |t| a , class AA (1/3 DIN B)
a |t| is the numerical value of the temperature in °C without consideration of the prefix.
