TELEDYNE ANALYTICAL INSTRUMENTS
Procedure: Cold starting an instrument.
Caution: This procedure deletes all previously stored data and test results, and resets the user
selectable parameters to their default values.
The Cold Start procedure can be a useful tool. It resets the instrument to factory set conditions
when the instrument is operating in an undesirable manner due to erroneous input or electronic
conditions. This procedure will also erase the password.
-------------------------------------------------------------------------------------------------------------------------------
Model 2000: Turn power off. Turn the power back on and while the introductory screen is
displayed (1 - 2 seconds) hold down the system button for about 7 seconds. This will erase any
calibration data such as zero and span. If you continue to hold the system button for more than
15 seconds all data will be erased.
Caution: This procedure will erase the calibration curve information stored in the curve algorithm
for linearization. The curve algorithms are configured at the factory to the user's application
specification. These functions should only be reprogrammed by trained, qualified personnel.
Note: The programming functions of the curve algorithm requires a password or a computer
connected to the RS-232 connector to satisfy the password protection feature. For instruments
with software 1.1.4 or later, turn the instrument off and back on. While on the introduction
screen hold the analyze key for at least 15 seconds to bypass the password protection feature.
-------------------------------------------------------------------------------------------------------------------------------
Model 2020: Turn power off. Turn power back on and while the introductory screen is displayed
(1 - 2 seconds) turn the enter/escape switch to the escape position for about 7 seconds. This
will erase any calibration data such as zero and span. If you continue to hold the escape
position for more than 15 seconds all data will be erased.
Caution: Same as for the Model 2000 (see above).
-------------------------------------------------------------------------------------------------------------------------------

Models 3000 and 3010: Turn power off. Turn power back on and momentarily press the system
button.
-------------------------------------------------------------------------------------------------------------------------------
Models 3020 T, P & M: Turn power off. Turn power back on and momentarily turn the
enter/escape switch to the escape position.
-------------------------------------------------------------------------------------------------------------------------------
Model 3160: See pages 4 - 5 of the model 3160 manual.
-------------------------------------------------------------------------------------------------------------------------------
Model 6000: Turn power off. Turn power back on and while on the introduction screen press the
system button for at least 15 seconds.
-------------------------------------------------------------------------------------------------------------------------------
Model 6020: Turn power off. Turn power back on and while on the introduction screen hold the
enter/escape switch to the escape position for at least 15 seconds.
-------------------------------------------------------------------------------------------------------------------------------
Model 7300 and 7320: Turn power off. Turn power back on and while on the introduction
screen press the enter button for 7 seconds to erase the calibration data such as zero and span.
If you continue to hold the enter button for at lease 15 seconds all data will be erased.
-------------------------------------------------------------------------------------------------------------------------------
Model 9070: See page 44, section 6.1 of the model 9070 manual.
-------------------------------------------------------------------------------------------------------------------------------
Model 9950: See pages 4 - 8 of the model 9950 manual.

Model MAX 5: (Clearing the Ram) Push the up & down arrow keys simultaneously.
Display: 1 thru 8
Push the down arrow key once. Push the enter key twice.
Display: O2=15%, Comb=0.00%, CO=0.00 PPM or %.
Remove the O2 cell and perform the procedure in the manual for electronic zeroing of the O2
sensor, page 20.
Re-install the O2 cell and perform AUTOCAL.
