NOTE: The warranty does NOT cover damage to probes or electronics that is caused by
exceeding temperature limitations, or damage to probes caused by using them in solvents
or other unsuitable environments.
NOTE:
If the displayed temperature shows a consistent high (> 100°C) or low (< -100°C) value,
most likely, the probe has failed.
Probe Installation
RTD sensors supplied with the LMS-188-4P should be installed using the supplied fittings,
which are 1/2” MNPT x 1/8” compression. After installing the fitting into a tee, insert the RTD
into the fitting and adjust the depth of the probe so as the tip of the probe is approximately at the
center of the piping. Tighten the nut finger tight, then with a small wrench turn the nut 1/4 to 1/2
turn past finger tight. Warning – do not overtighten.

Power-down Sequence
To power down the MPS and electronically disconnect the battery:
1. The power supply must be plugged in.
2. Press-and-hold the TEST/RESET button, until the MPS goes fully "dark" (LCD backlight
turns off and all LEDs are out).
3. Continue to hold the TEST/RESET button, and unplug the power supply.
4. Continue to hold the TEST/RESET button for 5 to 10 seconds.
5. Release the button.
If, when you release the button the MPS powers-up (in PowerFail mode), you will need to repeat
the procedure from step 1 by plugging the power supply back into an outlet.
