MM2030

MODEL MM2030 THERMOCOUPLE THERMOMETER / SIMULATOR FEATURES A high accuracy instrument that will give you confidence in your other instruments. The simulator was designed to simulate a known temperature as a cross-check on other instruments calibration accuracy. *** C / F / A switchable *** mV measurement / simulation capability *** Simulation mode for cross calibration checking *** Very High accuracy measurement instrument *** Resolution 0.1 to 1000 autoranging *** Switchable thermocouple types K / T / J / R / N / E / S *** Full retention of thermocouple type and temperature scale *** User configurable Auto Swith Off capability *** Overrange / Open circuit sensor indication *** Low battery indication *** Supplied complete with shock resistant holster *** IP67 casing The custom display is used to display the actual temperature the simulator is producing. When this coincides with the desired temperature the instrument is ready for use.

THERMOCOUPLE SIMULATOR ACCURATE TO WITHIN .0.1 C 3. TYPE K MINIATURE THERMOCOUPLE PLUG TO MINIATURE THERMOCOUPLE PLUG LEAD 4. COPPER MINIATURE THERMOCOUPLE PLUG TO COPPER MINIATURE THERMOCOUPLE PLUG LEAD CALIBRATION PROCEDURE The 2030 instrument has its own built in calibration sequence that is activated via the arrow buttons on the front panel 1. Switch the unit OFF. 2. Whilst holding down both the arrow buttons switch the unit ON. 3. The word CAL will appear in the top right hand corner of the display. 4. Connect the 30mV source and allow to settle. 5. Press the down arrow button. 6. A solid bar will appear on the left hand of the display. This indicates that the unit is calibrating. When the calibration is complete, the bar will be deactivated. 7. Connect the thermocouple simulator and set for 0 C type K , Allow to settle (approx 10 minutes) 8. Press the up arrow button. 9. A solid bar will appear on the left hand of the display. This indicates that the unit is calibrating. When the calibration is complete, the bar will be deactivated. 10. The unit should now be displaying 0.0 C. 11. Check that the calibration is in accordance with the figures shown in Table 1. If not then repeat procedure. 12. Switch the unit OFF. 13. The unit is now fully calibrated. NOTES 1. AUTO SWITCH OFF Whilst the unit is in CAL mode, if the SCL button is pressed the Auto-Switch off feature will be toggled. The state of the Auto-Switch off feature is shown in the top right hand side of the display next to the CAL message. If the Auto-Switch off is active the letter A will be displayed if not then no character will be shown.
