INTRODUCTION
ThefollowingprocedurewillallowyoutoeffectivelycalibrateyourMBT250/220
system to insure accuracy and maintain peak performance.
Perform the following procedure step by step, in sequence, to:
1. Alter Tip Temperature values.
2. Alter Tip Temperature Offset values.
3. Determine and/or alter feature status and defaults stored in the system.
4. Recalibrate the system for accuracy.
PROCEDURE
KEYLOCK OPTION
1. An optional KeyLock feature is available
from PACE which prevents unauthorized
alteration of stored data or calibration of
the system. Check the rear panel of the
system power source. If the KeyLock
feature is present there will be a KeyLock
switch located in the upper left portion of
the panel. Use the key to turn the switch
to the “Unlock” position. If the feature is
not present, there will be a round plastic
filler plug present at that location.
NOTE
TheKeyLockswitchmustbeturnedtothe“UNLOCK”positiontoalterany
of the data stored in memory or to recalibrate the system.

3. Press and hold the Tip Temperature Set
and Scroll Down Keys.
4. PlacePOWERSwitchinthe“ON”(1)
position. Allof the system LEDswilllight.
TheTemperatureDisplaywillread“888”
and change to read “1-X”.
5. Release the TipTemperature Set and Scroll
DownKeys. TheTemperatureDisplaywill
now read “CAL” and only the three
ChannelLEDswillremainlitsignifying
that the system is now in the Calibration
Mode.
°F/°C READOUT DEFAULT
6. Press and release the Tip Temperature Set

Key. The Digital Readout will display
“S-X”(X=1-9).Eitherthe°For°Cwill
be on. This is the default readout (e.g., if
the°CLEDis ontheDigitalReadoutwill
display temperature readings in °C).
7. Press and release the °F/°C Key to
change the default. Each subsequent
press and release of the key will change
the default.
AUTOMATIC SETBACK
8. As received from the factory, the
temperaturewillread“S - -” meaning that
Automatic Setback is turned off. A
readout of 1 thru 9 on the right side of the Digital Readout indicates time
toAutomatic Setback inincrementsof10minutes. Forexample,“S-3”
would indicate a timeout of 30 minutes.
To change the Automatic Setback
feature, press the Scroll Up Key to
increase the timeout and/or enable the
feature. Press the Scroll Down Key to
decrease the timeout.
9. Press the Tip Temperature Set Key to
store the °F/°C default andAutomatic
Setback value in system memory. The
DigitalReadoutwillreverttodisplay
“CAL”andonlytheChannel1LEDwill
remainlit.

10. The system enables the Automatic
Shutdown feature only when the
Automatic Setback feature is
enabled. No additional steps are
necessary.
CHANNEL SELECTION
11. TheChannel1LEDis nowlit
signifying that Channel 1 is ready for
calibration. Performsteps12
through 21 to calibrate. As channels
change, repeat these steps for each
channel.
NOTE
All temperature limits are stored in
system memory in degrees F.

14. Press and release the Tip Temperature Set
Key to store the display value into
memory.

MESSAGE DESCRIPTION
DESCRIPTIONDESCRIPTION
DESCRIPTION
C-1 OR C-2 Indicates system is ready to process Digital Readout accuracy
calibration for a particular channel using the appropriate
calibration module.
CAL Indicates that system is in the Calibration Mode.
E-5 Input to control circuitry unstable. Indicates that no calibration
module is connected to the channel being calibrated or the
incorrect module has been inserted.
E-6 Loose connection. Calibration input is out of range. Normally
occurs if incorrect calibration module is inserted.
H-X
(X = 1 thru 9) Indicates the Current Channel is ready to accept new Upper Temperature Limit setpoint X (X times 100°F).
L-X
(X = 1 thru 9) Indicates the Current Channel is ready to accept new Lower Temperature Limit setpoint X (X times 100°F).
OFF Setpoint for this channel is below Lower Temperature Limit
setpoint.
S-- Indicates that the Automatic Temperature Setback (and Power
Down) feature is disabled (turned off).
S-X
Indicates that the Automatic Temperature Setback (and Power
Down) feature is enabled (turned on) and will set each channels'
Set Tip Temperature back after X times 10 minutes of handpiece
inactivity (non-use).
---
(flashing) Indicates that the system circuitry is proceeding with calibration using the proper calibration module (C-1 or C-2).
