4. To clear minimum and maximum readings from memory, press and hold “RST” (reset) button until the entire display flashes. Release the button and the current relative humidity and

temperature are displayed. New minimum and maximum relative humidity and temperature readings will be recorded into memory.

Data Hold Function
1. Press “HOLD” button until “HLD” appears in display. The current reading is now being held and will not change until the hold function is cancelled.
2. To cancel the hold function, press the “RST” (Reset) button.
3. The “HOLD” feature will hold the readings for dew point, relative humidity and temperature.

Dew Point Function
1. Press and hold “td” button until “td” appears on the display. The current dew point temperature is displayed
2. To cancel the dew point temperature reading and return to normal temperature display, hold “td” button until “td” disappears from the display.

Auto Power Off Feature
1. Unit will turn itself off after 20 minutes. To return to the display, press ON/OFF button.
2. To override Auto Power Off mode, turn the unit off and press the “ON/OFF” and “MN/MX” button simultaneously. After the full display appears, release the “ON/OFF” button. When “n”
