Example limits calculations
Model 2601/2602 example
As an example of how verification limits are calculated, assume you are testing
the Model 2601/2602 6V DC output range using a 5.4V output value. Using the
Model 2601/2602 one-year accuracy specification for 5.4V DC output of ± (0.02%
of output + 1.8mV offset), the calculated output limits are:
Output limits = 5.4V ± [(5.4V × 0.02%) + 1.8mV]
Output limits = 5.4V ± (0.00108 + 0.0018)
Output limits = 5.4V ± 0.00288V
Output limits = 5.39712V to 5.40288V
Model 2611/2612 example
Similarly, assume you are testing the Model 2611/2612 20V DC output range
using an18V output value. Using the Model 2611/2612 one-year accuracy
specification for 18V DC output of ± (0.02% of output + 5mV offset), the calculated
output limits are:
Output limits = 18V ± [(18V × 0.02%) + 5mV]
Output limits = 18V ± (0.0036 + 0.005)
Output limits = 18V ± 0.0086V
Output limits = 17.9914V to 18.0086V
Restoring factory defaults
Before performing the verification procedures, restore the instrument to its factory
front panel (bench) defaults as follows:
1. Press the MENU key. The instrument will display the following prompt:
MAIN MENU
SAVE-SETUP COMMUNICATION TEST
2. Select SAVE-SETUP, and then press ENTER. The unit then displays:
SAVE SETUP MENU
SAVE RECALL POWERON
3. Select RECALL, and then press ENTER. The unit displays:
RECALL SETUP
FACTORY USER-1 USER-2 USER-3 USER-4 USER-5
4. Select FACTORY, then press ENTER to restore defaults.
