Overview of the Adjustment Process
The TekScope instrument is protected from inadvertent adjustment by an internal
adjustment-lockout jumper. Some disassembly is required to access and remove
the jumper before you can adjust the instrument. After adjustment is complete,
the jumper should be replaced to protect the calibration of the instrument.
Oscilloscope adjustment and meter adjustment are independent procedures. You
can choose to adjust either or both. Each procedure consists of a series of steps;
as you move through these steps, the TekScope instrument display provides
instructions that describe the specific input signal requirements for each step.
NOTE. During some steps, the instrument may appear to be idle for several
minutes while it is processing information internally. Please have patience.
If all steps in the procedure are completed successfully, a “Pass” message is
displayed and the new calibration constants take affect. If any step fails, the
procedure is aborted and the current calibration is not affected. You can also
choose to abort the procedure at any step.
Before performing adjustment procedures, you must warm up the instrument at
least ten minutes in an ambient temperature between 20° C and 30° C. Adjust-
ments performed prior to warm-up or outside this temperature range may result
in poor performance.
In this manual, TekScope instrument setups are shown in tables. Refer to
Conventions on page x for information about how to use these tables.
