To STORE TEMPS IN MEMORY: When you have taken a full (or partial) set of
temps you can store them for recall later. Simply push "Store in Memory" and any
Memory button - 1 to 10 - AT THE SAME TIME. A double beep will indicated that
these temps are stored. If there are already temps in this Memory location a mes-
sage will come up:
THIS MEMORY IS FULL THIS MEMORY IS FULL THIS MEMORY IS FULL THIS MEMORY IS FULL THIS MEMORY IS FULL
CHOOSE ANOTHER OR CLEAR CHOOSE ANOTHER OR CLEAR CHOOSE ANOTHER OR CLEAR CHOOSE ANOTHER OR CLEAR CHOOSE ANOTHER OR CLEAR
If you no longer need those temps in Memory push the "Clear Memory" and that
Memory number button and hold both for 2 seconds. A double beep will indicate
that the Memory has been cleared. Now you may store the current temps in that
Memory location.
To RECALL TEMPS: Simply push and hold any of the Memory buttons.
Misc. Notes:
■ The probe tip must be small to give rapid response. There is no other way to do it. This makes it somewhat
delicate and easily damaged! Please treat the probe with care and don't allow it to get bent. Use the yellow
protector. A DAMAGED PROBE TIP CANNOT BE REPAIRED AND WILL NOT BE WARRANTIED.
■ This unit shuts off automatically 5 minutes after the last button is pushed. However no temps are lost.
Simply turn the unit back on and continue.
■ A low battery indicator comes in the display. When needed replace with a good quality Alkaline 9 volt
battery. The door is on the bottom side. In normal use the battery should last 3 months or more.
■ Temp limit is 300 O F. A different model reading in O C is available. Contact your dealer or the factory.
■ For reference: one beep indicates that you have pushed a button, 2 beeps indicate that the pyrometer has
done something - Cleared Display for example, and 3 beeps indicates an error of some sort.
■ Several pre programed messages may appear to inform you of options. They will be self explanatory.
■ For consistant readings always measure the tires the same distance from the edges and push the probe into
the tire to the same depth each time.
■ The probe plug has a wide and a narrow spade. Do not plug the probe in backwards. If you do the pyrom-
eter will read reversed - the hotter the probe gets the lower the temps will read.
■ Keep this unit out of extreme heat or cold. If the pyrometer is very cold the display response time may be
slower. This does not affect its ability to accurately measure temps. The electronics are fully temperature
compensated. Take readings in the normal way. In extreme heat the display may not be visable. Allow it to
cool off and recheck. Do not leave in direct sunlite for an extended time.
■ A quick calibration check can be made with boiling water. Temp should read 208 to 212, depending on your
altitude above sea level.
