INPUT SPECIFICATIONS
■ DC Current
Current range: Approx. 3.7 to 23 mA DC
Voltage drop: Approx. 5 V with 4 mA; approx. 5.2 V with 20 mA (Equivalent input impedance: Approx. 260 Ω)
(There is voltage drop generated by using the unit.  For the two-wire transmitter power supply, make sure that the operable voltage for the two-wire transmitter is ensured including the voltage drop by other devices and wiring resistance.)

INSTALLATION
Operating temperature: -10 to +55°C (14 to 131°F)
Operating humidity: 30 to 90 %RH (non-condensing)
Mounting: Panel flush mounting
Weight: 160 g (0.35 lb)

PERFORMANCE
Accuracy: ±0.1 % rdg ±1 digit ("1 digit" is multiplied by scaling-multiple. Even in case the scaling-multiple is less than 1, multiply by 1.)
Temp. coefficient: ±(0.01 % rdg +0.3 digits)/℃
("0.3 digits" is multiplied by scaling-multiple. Even in case the scaling-multiple is less than 1, multiply by 1.)
Scaling-multiple = | (Display Scaling Value B - Display Scaling Value A) ÷ (default Display Scaling Value B - default Display Scaling Value A) |
