1. Remove the battery door on the back of the sensor by removing the set screw, as shown in Figure 1 . Figure 1 2. BEFORE inserting the batteries, locate the dip switches on the inside cover of the lid of the transmitter. Figure 2 displays all four switches in the OFF position (factory default setting). Figure 2 3. Channel Number: The WS-07 supports up to eight transmitters. To set each channel number (the default is Channel 1), change Dip Switches 1, 2 and 3, as referenced in Table 1. 4.

Insert two AAA batteries. 6. After inserting the batteries, the remote sensor LED indicator will light for 4 seconds, and then flash once per 60 seconds thereafter. Each time it flashes, the sensor is transmitting data. 7.

Figure 4 All of the LCD segments will light up for a few seconds to verify all segments are operating properly. 3. Replace the battery door, and fold out the desk stand and place the console in the upright position. The console will instantly display indoor temperature and humidity as designated by the icon. The remote temperature and humidity will update on the display within a few minutes on the appropriate channel. While in the search mode, the remote search icon will be constantly displayed.

Channel 1,2,3,4,5,6,7,8, indictor 2.3.2 Sensor Operation Verification Verify the indoor and outdoor humidity match closely with the console and sensor array in the same location (about 5 to 10’ apart). The sensors should be within 10% (the accuracy is ± 5%). Allow about 30 minutes for both sensors to stabilize.

3 Remote Sensor Installation It is recommended you mount the remote sensor on a north facing wall, in a shaded area. Direct sunlight and radiant heat sources will result in inaccurate temperature readings. Although the sensor is water resistant, it is best to mount in a well protected area, such as under an eve. Use a screw or nail (not included) to affix the remote sensor to the wall, as shown in Figure 6. Figure 6 4 Display Features 4.

2. Clear Maximum. To reset the maximum values to the current values, press and hold the CLEAR button for 3 seconds. 3. Display Minimum. Press the MIN/MAX button again to display the minimum. The MIN icon will be displayed. 4. Clear Minimum. To reset the minimum values to the current values, press and hold the CLEAR button for 3 seconds. To return to normal mode, press the MIN/MAX button again. 5.

The following is a table of reception loss vs. the transmission medium. Each “wall” or obstruction decreases the transmission range by the factor shown below. Medium Glass (untreated) Plastics Wood Brick Concrete Metal RF Signal Strength Reduction 5-15% 10-15% 10-40% 10-40% 40-80% 90-100% 5.6 Adjustment or Calibration Note: The calibrated value can only be adjusted on the console. The remote sensor(s) always displays the un-calibrated or measured value.
PAGE 10
Official stations recalibrate or replace humidity sensors on a yearly basis. Due to manufacturing tolerances, the humidity is accurate to ± 5%. To improve this accuracy, the indoor and outdoor humidity can be calibrated using an accurate source, such as a sling psychrometer: http://www.ambientweather.com/mafaredspslp.html or one step humidpak calibration kits (reference Section 9). You can also use common table salt, water and a plastic bag: http://ambientweather.wikispaces.com/ws07 5.6.

6 Glossary of Terms Term Definition Accuracy is defined as the ability of a measurement to match the actual value of the quantity being measured. A hygrometer is a device that measures relative humidity. Relative humidity is a term used to describe the amount or percentage of water vapor that exists in air. Range is defined as the amount or extent a value can be measured. Accuracy Hygrometer Range 7 Specifications 7.

Problem There are dashes (--.-) on the display console. Solution and the remote search icon will be constantly displayed. Once the signal is reacquired, the remote search icon will turn off, and the current values will be displayed. The maximum line of sight communication range is 300’ and 100’ under most conditions. Move the sensor assembly closer to the display console. If the sensor assembly is too close (less than 5’), move the sensor assembly away from the display console.
