Calibrating OM-WEB Series hardware
OM-WEB Series hardware is calibrated to the selected device settings each time the
Submit

Calibrate
button
is pressed on a web interface configuration page, or the
OK

configuration page.
Warm-up period
After you configure the hardware options, allow the OM-WEB Series device to warm up for 30 minutes before
taking measurements. This warm up time minimizes thermal drift and achieves the specified rated accuracy of
measurements. For analog, RTD or thermistor measurements, this warm-up time is also required to stabilize the
internal current reference.
