VARIOUS OPERATING MODES

DIGITAL HOLD

DIGI1 will hold the display for IN1

DIGI2 will hold the display for IN2

ALARM OUTPUTS

Applications that feature an alarm can be connected as above.

ALM1 and ALM2 must not sink more than 10mA maximum.

If supply voltage varies, use an appropriate voltage regulator.

MEASURING 4-20mA

Use a 50 Ω resistor with a 200mW rating.

Setup scaling in software 0V=4.0 and 1V=20.0

Cannot be loop powered. Supply must be isolated for current loop.
