2. Type K Thermocouple Input
3. LCD Display
4. Display Hold / Mode Button
5. Light Sensor
6. Humidity/Temperature sensors
7. Power/Backlight button
8. MAX-MIN Record/Enter Button

Operation

Meter Power

1. Three (3) 1.5V ‘AAA’ batteries power the meter. The battery compartment is located on the rear of the meter secured by one flat head screw.
2. Short press the power button to switch the meter ON. The meter will begin displaying readings for the mode selected.
3. Long press the power button to power OFF the meter.

Auto Power OFF (APO)
In order to conserve battery life, the meter will automatically switch off after approximately 10 minutes of inactivity. Note that APO does not function while the meter is in the MAX -MIN Recording mode
(short press the R button to access the MAX-MIN Recording mode).

Selecting the Operating Mode
Long press the M (Mode) button to scroll through the list of functions. When the desired mode is displayed, release the button. See display icons with brief descriptions below:

• dbSound Level(dBA)
• rHRelative Humidity in % and Air temperature
• dPDew point temperature
• EtWet bulb temperature
• HEATtHeat index temperature
• LigHtLight intensity measurements
• tYPEType K thermocouple temperature (must attach thermocouple to meter)

Changing the Units of Measure

• Press and hold the R button until the word ‘Unit’ appears.
• Now short press the power button to change the units for the selected measurement mode.
• Short press to save the selection and move to the secondary function, if applicable (temperature, for example). Short press the power button to change the secondary function units, if applicable, and then short press to save.
• See units list below:
  • Sound dB
  • Temperature units oC, oF (for air, dew point, wet bulb, heat index, and Type K)
  • Light units    Foot-candles, LUX

Reversible Backlight LCD

• The LCD display automatically reverses its presentation orientation depending on measurement mode. This is to match the display orientation with the selected sensor mode (light or environmental measurements such as Wet bulb temperature).
• The LCD is equipped with backlighting for easier viewing, especially in dimly lit areas. With the meter powered ON, short press the power button to turn ON the backlight. The backlight will power OFF after several seconds.

Display Hold
Short press the H (Hold) button to freeze and unfreeze the displayed reading. The Display Hold mode is not operational when using the MAX-MIN Recording mode.

MAX-MIN Record Mode

• In this mode, the meter records the maximum and minimum readings over time.
• Short press the R (Record) button to start recording MAX/MIN readings.
• Now use short presses of the R button to toggle MAX and MIN reading displays.
• Short press the H button to reset MAX and MIN memories.
• Press and hold the R button to exit the Recording mode.

Measurement Modes

Sound Level Measurement

1. With the meter ON, press and hold the M (Mode) button until ‘db’ is displayed; then release the button.
2. The meter will stard measuring the sound in dB.

Light Measurements

• Press and hold the M button until ‘LigHt’ is displayed; then release.

• Hold the meter so that the source of light fully encompasses the light sensor dome.

• View the light reading on the LCD (light readings are displayed in reverse orientation).
  Type K /Relative Humidity/Dew point/Wet bulb/Heat index Measurements

• Press and hold the M button until the desired function is displayed:

• ; rH Relative Humidity (with air temperature); dP Dew point; _Et Wet bulb; HEAt Heat index; tYPE Type K thermocouple temperature (attach thermocouple to meter)

• Place the meter or type K probe in the measurement area and view the readings on the LCD.

Maintenance

Battery Replacement

When the low battery icon appears on the display please replace the batteries as described below.

1. Remove power from the meter.
2. Remove the flat head screw that secures the battery compartment at the back of the meter.
3. Open the battery compartment and replace the three (3) 1.5V ‘AAA’ batteries observing correct polarity. Re-assemble the meter before use.

Safety:
Please dispose of batteries responsibly; never dispose of batteries in a fire, batteries may explode or leak. If the meter is not to be used for 60 days or more, remove the batteries and store separately.

Never dispose of used batteries or rechargeable batteries in household waste.
As consumers, users are legally required to take used batteries to appropriate collection sites, the retail store where the batteries were purchased, or wherever batteries are sold.

Disposal:
Do not dispose of this instrument in household waste. The user is obligated to take end-of-life devices to a designated collection point for the disposal of electrical and electronic equipment.

Cleaning and Storage

Periodically wipe the case with a damp cloth and mild detergent; do not use abrasives or solvents. Do not allow moisture to come in contact with any of the sensors.
