WLS-TEMP Specifications

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.
