Auto Tip Temperature Compensation; Password - Pace ST 40A Operation & Maintenance Manual

TIP TEMPERATURE OFFSET - Difference in value between the temperature
measured by the temperature sensor (at the heater) and the true temperature of the tip
at a given Set Tip Temperature.
As with any system, Set and Operating Tip Temperatures are only exactly
equal when the handpiece is idling (unloaded at equilibrium). During use,
(i.e., under load) the Operating Tip Temperature will usually be lower.

Auto Tip Temperature Compensation

Differences between the temperature settings and true tip temperatures are
negligible when using Thru-Hole, single point soldering tips. With any heating
system however, True Tip Temperatures can differ greatly from temperature settings
when using larger SMT soldering tips. This difference is called Tip Temperature
Offset. The ST 40A Auto Tip Temperature Compensation feature lets you set and
display true tip temperatures regardless of size and type of tip or handpiece. PACE
recommends the use of the Tip & Temperature Selection System booklet (PACE
P/N 5050-0251) as a guide to accurately set and maintain a true tip temperature for
any size and type of SMT tip.

Password

The Password feature of the ST 40A system, when activated, will prevent
unauthorized alteration of stored system temperature parameters and feature
settings (refer to Table I, "Factory Settings"). If a Password has been installed,
the Digital Readout will display an instruction to enter the Password (a 4 key
sequence of the keys on the system front panel) when a setting change is
attempted.
Entry of the correct Password at this point will allow the operator to proceed
with the desired changes. Once the correct Password has been entered, the
operator can continue to make changes to Tip Temperature and Tip Temperature
Offset settings. To reactivate the Password protection, simply press either the
Scroll Up or Scroll Down key when the system is in the Temperature Display
Mode (normal operation). The Password protection will also be reactivated if
the system is turned off and then back on. Refer to the "Set-Up Mode" section
of this manual for instructions on entering, changing or removing a Password.
