How to fix a UEi Thermometer that won't turn on?
If your UEi Thermometer isn't turning on, the issue is likely related to the battery. First, try replacing the battery with a fresh one. If that doesn't work, make sure the battery clip grips the battery posts tightly to ensure a secure connection.
Why does the temperature reading on my UEi Thermometer drift from a known value?
If the temperature reading on your UEi Thermometer drifts from a known value, several factors could be responsible. First, ensure the thermocouple type matches the displayed icon. Moisture, corrosion, or debris on the thermocouple can also cause inaccurate readings, so clean and dry the thermocouple blades and allow the plug to air dry. Finally, the thermocouple itself may be defective; confirm this with a known good thermocouple and replace it if necessary.
What to do if dashes appear on the UEi DT200 screen even with thermocouples inserted?
If you see dashes on the T1 and/or T2 data screens of your UEi Thermometer despite having thermocouples inserted, it could be due to thermocouple continuity or connection issues. Measure the resistance of the thermocouples to ensure they are not broken internally; replace them if needed. Also, check the thermocouple connections for corrosion or debris; clean them off and reinsert the thermocouples.
Why does UEi DT200 Thermometer data keep updating when HOLD or RECORD are on?
If the data on your UEi Thermometer continues to update even when HOLD or RECORD is activated, it's likely that the Hold/Record button is not being fully pressed. These functions only affect the primary screen information. Observe the HOLD or REC icons on the LCD and press the button firmly to ensure proper engagement.
Why do dashes appear when reviewing the maximum recorded value on my UEi Thermometer?
Dashes appearing during the review of the maximum recorded value on your UEi Thermometer suggests an open thermocouple. Check for an intermittent or momentarily removed thermocouple.
Why does my UEi DT200 turn off while recording?
If your UEi Thermometer turns off during recording, follow the procedures outlined in the operating instructions to disable the auto power off feature.
Why won't the relative clock start on my UEi DT200 when I press the RECORD button?
The relative clock on your UEi Thermometer will not start if thermocouples are not properly inserted. Ensure that thermocouples are inserted.
Why do dashes appear in the T1 and T2 data screens of my UEi DT200 Thermometer?
If dashes appear in the T1 and T2 data screens of your UEi Thermometer, it indicates that thermocouples are missing. Insert the missing thermocouples.
