Keithley 2000 Calibration Manual

Front panel calibration
Follow the steps in the following paragraphs for comprehensive, DC only, and AC only cali-
bration procedures.
The procedures for front panel calibration include:
• Preparing the Model 2000 for calibration
• Front panel short and open calibration
• DC voltage calibration
• Resistance calibration
• DC current calibration
• AC voltage calibration
• AC current calibration
• Setting calibration dates
Preparing the Model 2000 for calibration
1. Turn on the Model 2000, and allow it to warm up for at least one hour before performing
the calibration procedure.
2. Select the DCV function and choose SLOW as the RATE (integration time = 10 PLC).
3. Start the calibration process as follows:
A. Access the calibration menu by pressing SHIFT then CAL.
B. Use the up and down range keys to scroll through the available calibration menu
items until the unit displays RUN, then press ENTER.
C. At the prompt, enter the calibration code. (The default code is 002000.) Use the left
and right arrow keys to move among the digits; use the up range key to increment
numbers, and press the down range key to specify alphabetic letters. Confirm the
code by pressing ENTER.
D. Choose N at the prompt to proceed without changing the code, then press ENTER.
4. Choose which of the the calibration tests summarized in Table 2-2 you want to run at the
CAL: RUN prompt. Use the up and down range keys to scroll through the options; select
your choice by pressing ENTER.
