Restoring factory default settings
You can restore the factory default configuration settings with InstaCal.
Connecting the external power supply for remote operation
Connect the USB cable to the AC-to-USB power adapter when you are operating the WLS-TEMP remotely
through the wireless interface. The
Command and Wireless Power LEDs turn on approximately five seconds
after you connect the AC power adapter.
Caution! To satisfy FCC RF exposure requirements for mobile transmitting devices, maintain a separation
distance of 20 cm (0.66 feet) or more between the antenna of this device and personnel during
device operation. To ensure compliance, operation at closer than this distance is not
recommended. The antenna used for this transmitter must not be co-located in conjunction with
any other antenna or transmitter.
Calibrating the WLS-TEMP
You can fully calibrate the WLS-TEMP using InstaCal. Allow a 30-minute warm up before calibrating.
InstaCal prompts you to run its calibration utility if you change the sensor category. If you don't change the
sensor category the normal calibration interval is once per year.
You can calibrate the WLS-TEMP when it is connected locally to the computer through the USB port, or when
it is operated remotely through the wireless interface.
Warm up time
Allow the WLS-TEMP 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 RTD or thermistor measurements, this warm-up time is also required to stabilize the internal current
reference.
