Setting the Meter

SETUP Options
Press the SETUP button to enter into setting mode, “SET” flashes on the LCD, continue to press the button to step through and save the following setup options and exit the mode.

Performing the Setups

1. Setting Temperature Unit
   Press SETUP to access Temperature Unit setup mode, “Unt” shows on LCD.
   Press ▼(HOLD)/▲(Max/Min) to select the ℃ or ℉ unit.

2. Setting Time Interval
   Press SETUP to switch to time interval mode, “int” shows on LCD. Press▼▲ to change the interval for automatic data storage. Long press ▼▲ to increment the time quickly.
   The interval can be set up to 59:59 and down to 00:00(auto data storage disabled at 00:00).

3. Setting Humidity Offset
   Press SETUP to switch to humidity offset mode, “H-O” icon shows. Press ▼▲ to change the offset value that ranges within -6~+6.

4. Setting Temperature Offset
   Press SETUP to switch to temperature offset mode, and the “t-o” icon shows. Press ▼ ▲ to change the offset value that ranges within -6~+6.

5. Setting Dew Point Offset
   Press SETUP to switch to dew point offset mode, and the “d-o” icon shows. Press ▼▲ to change the offset value that ranges within -6~+6.

6. Setting Sleep Mode
   Press SETUP to switch to sleep offset mode, “SLP” icon shows. Press ▼▲ to set up sleep time(5~60mins). Long press ▼▲ to increase the time quickly; When the set time is ＜5mins, the “OFF” icon shows, and the sleep function are disabled.

7. Setting System Time
   Press SETUP to switch to system time mode, and the “S-t” icon shows. Press ▼▲ to set up system time. Long press ▼▲ to increase the time quickly; Press ENTER to select time format “h:m” or “m:s”. To make it easy for the user, the “m:s” format will be automatically converted into “h:m” after the system time exceeds 60 seconds.

Using the Meter

• Turn on/off Power Save Mode

1. Press the yellow button to turn on the Meter;
2. When the Meter turns on, it defaults to factory setup.
3. With the meter already turned on, pressing the yellow button again will turn off the Meter (UT331);
4. with the meter already turned on, press the yellow button again will go into power save mode (UT332, “ ” shows on LCD upper left corner). Repress to exit the mode.
5. Set the sleep mode, the Meter will enter power save mode if no button is active within the set time.
6. To ensure an accurate result, the user is recommended to wait for a while before taking the readings if the measured humidity &temperature change dramatically.

• Data Hold
  Press the HOLD button to freeze the reading, “HOLD” appears on the LCD. Press again to quit the function.

• Turn on/off Backlight
  Under normal measurement status, press “ ” button to turn on the backlight.
  Press again to turn it off.(the backlight is off under power save mode).

• View Max/Min Reading
  Press MAX/MIN button to check Max. and Min. readings. Long press the button to exit the mode.

• View Dew Point Temperature
  Press ENTER to check the dew point temperature, “DEW POINT” icon is indicated on the LCD. Press again to quit the function.

• Store and Recall Data
  Press the STORE button, and the Meter will save the data into its memory and store up to 100 sets of data (00–99).
  The recorded data are those shown on the primary display. Press the button again to exit the function.
  Press RECALL to review the data stored in the memory. Press again to exit the function.

1. Store Data
   Press the STORE button and the “DATA” icon shows on the upper part of the LCD. There are two ways to store data.
   Manual Method: Preset time interval for auto storage at 00:00(refer to “Setting Time Interval” section), then get into STORE mode, press ENTER once to save current reading into the current address of the memory, press ENTER again to save into the next address. Press ▼▲ to change the address to store. “—-” shows for blank address.
   Auto Method: Preset time interval not at 00:00, then get into STORE mode, press ENTER once, “:” icon flashes, and the Meter will save the data in order into the memory by beginning with the current address and storing at an interval previously set.
