①Using for measuring of temperature solely
１ When use for the first time, remove the lid of the battery
compartment with a No. 1 Phillips screwdriver, and road
four new R6 batteries according the direction.
Settle the H-769 on a level and stable place.
Turn the power switch on. The unit rises buzzing “Pipi!”
and begins to display the room temperature on the main
letters.
Gently place the tip of energized soldering iron, the tem-
perature of which must be stable, on the center of the
sensor. Note the reading on the main letters. To
improve heat transfer from the soldering iron tip to the
sensor, apply a small amount of solder.
Solder flux builds up on the sensor. Wipe off periodically
with suitable cleaning liquid such as the HOZAN Z-293
FLUX REMOVER.
The sensor is a consumable item. “999” will displayed
when worn out. Simply remove the sensor as illustrated,
and replace it with a new sensor.
After having executed calibration or exchanging the sensor, the displayed temperature
may change as before.

Saving data
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 analyz-
ing 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 becomes
stable.
→ Narrow the criterion not to start measurement until the temperature of the
soldering tip becomes more stable. (Refer to page 18.)
