Password; Auto Tip Temperature Compensation - Pace ST 85 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.

Password

The Password feature of the ST 85 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 LED
Display will display an instruction to enter the Password (a 5 key sequence of the
keys on the system front panel) when a setting change is attempted.
Once the correct Password has been entered, the operator can proceed to make the
desired setting changes. To reactivate the Password protection, simply turn the
system Power Switch off and then back on. The system is now in normal operation.
Refer to the "Set-Up Mode" section of this manual for instructions on entering,
changing or removing a Password.

Auto Tip Temperature Compensation

Differences between the temperature settings and true tip temperatures are negligible
when using Thru-Hole, single point desoldering 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 85 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. The booklet contains a listing of PACE tip information
including the Tip Offset Constant (for each tip) which must be stored in system
memory to ensure tip temperature accuracy. Refer to the "Set-Up Mode" section
of this manual for instructions on using this feature.
