key. Then, place

the probe in the location you want to

measure gas concentration.

TEMP Key

The meter will always display tempera-

ture readings from the permanent sensor

on the lower line of the display. When

you wish to take an external tempera-

ture reading using an RTD probe, plug

any three-pronged RTD probe into the

right side. Then, press the TEMP key to

view the temperature from the resistive

temperature detector (RTD). The letters

“Prb” will display on the top line of the

display and the actual temperature from

the RTD on the bottom line.

To return to reading temperatures from

the permanent probe, press the TEMP

key again.

Note: If the external RTD probe becomes

unplugged while in “Prb” mode, the display

will read “over.” If the RTD probe is not

plugged in and the TEMP key is pressed,

nothing will happen.
