Temperature Measurement Device (TMD-02)
Your appliance is equipped with a temperature measurement device (TMD) also referred to
Thermometer/Alarm that simultaneously displays minimum, maximum, and current interior temperatures
and provides a visual and audible signal when the temperature inside the unit falls outside the set
temperature range.
NOTE: When you first receive your appliance, the TMD-02 is powered off. It will need to be turned on
before use. To turn the TMD on, press and hold the button for five seconds.
NOTE ABOUT CALIBRATION: Models with NSF456 suffix are equipped with a NIST-calibrated TMD-02.
A two-year certificate of calibration is included in the alarm/thermometer box that comes inside your unit.
Keep this certificate stored safely for your records. EQTemp
®
offers re-calibration services through their
ISO 17025:2017 certified calibration laboratory. It is recommended to have your TMD re-calibrated every
two years (or one year, depending on your state’s health department guidelines). For more information on
how to have your device re-calibrated or to replace a valid certificate, contact us at
calibration@summitappliance.com.
The temperature sensor, or probe, is enclosed in a glycol or glass bead-filled bottle that is stored inside
your unit in a special shelving compartment.
