Temperature Humidity Meter Operation Pressing S saves the present readings to a memory location. L and the memory location number appear in the display to indicate the readings have been stored. Press W to return the display to the present reading. After all 99 memory locations are filled, each subsequent save overwrites a memory location starting with the first. To recall the readings from memory, press R. If the memory location you are looking for is not already displayed, press ▲ or ▼ until the desired memory location is displayed. To return the Meter to normal operation, press R for two seconds. By default, relative humidity and ambient temperature are displayed when a memory location is recalled. Pressing W cycles through the Wet Bulb, Dew Point, and Ambient temperatures stored in the memory location displayed. To erase all 99 memory locations, simultaneously press S and R for five seconds. Automatic Power Off To save battery life, the Automatic Power Off (APO) feature can be used to turn the meter off after 20 minutes of no activity. To enable or disable the APO feature, remove the battery cover and position the APO switch to the desired position. See Figure 1. 5
