3. Power on the meter by pressing the "Power Button" (3-2, Fig.1). The Display will show the text "Sound" once a while then return to normal screen (Display unit is dB). Now the whole system (meter + sound adapter) is ready for the sound level measurement. The display will show the measured sound value with unit "dB".

Type K/J thermometer

1. Function select to "Type K/J thermometer"
2. Plug the Thermocouple Temp. Probe (Type K Temp. probe or Type J Temp. probe, optional) into "Type K/J Probe Input Socket" (3-8, Fig. 1)
   The Display will show the measuring value that sensing from the Temp. probe.
