Front panel calibration
Use the following steps for comprehensive, DC-only, and AC-only calibration procedures.
The procedures for front panel calibration include:
• Preparing the Model 2010 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 2010 for calibration
1. Turn on the Model 2010, and allow it to warm up for at least two hours before performing
calibration procedure.
2. 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, and then press ENTER.
C. At the prompt, enter the calibration code. (The default code is 002010.) 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, and then press
ENTER.
3. Choose which of 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.
