Operation
When recording and judgment start, the LCD displays ●REC.
The remaining seconds are displayed on the sub letters, counting down, 4...3...

Judgment“NG” is displayed if the temperature goes out of the set temperature and set time, and “OK” blinks when the set temperature ismaintained.

Saving data

When recording is completed, ●REC sign goes out and thedata are saved in the SD card.
Do not remove the SD card during the bar is spinning on the
sub letters since it is under data saving. This could damage
the data in the SD card.

Next measurement

The temperature of the sensor part must be higher if continuously measured temperature after that. Next measurement can
not be done until the displayed value falls than the set value (inthis case: 200℃).

Please configure good/NG judgment function
The displayed temperature on this soldering iron thermometer is influenced by seasons,locations, the manner of placing the soldering tip onto the sensor and any other factors.
Please make up your good/NG criterion and use this function after recording and analyzing multiple samples under various circumstances.
If a soldering iron, which is working properly, is judged as “NG”, there is a possibility that
judgment and recording start at inappropriate timing. Check below.
・The heat of the soldering tip, whose temperature has been already stable, isn’t
efficiently conducted to the sensor.
→ Supply more solder onto the sensor and the soldering tip.
・Judgment and recording start before the temperature of the soldering tip becomesstable.
→ Narrow the criterion not to start measurement until the temperature of thesoldering tip becomes more stable. (Refer to page 18.)
