Restoring Factory Defaults; Performing The Verification Test Procedures; Test Summary; Test Considerations - Keithley 3700 series Reference Manual

Section 10: Verification
For example, assume that you are testing the 10k range using an actual 10.03k calibration
resistance value. Using Series 3700 one-year 10k range accuracy of  (60ppm of reading +
4ppm of range), the calculated reading limits are:

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.
2. Turn the wheel to highlight SETUP and then press the ENTER key.
3. Turn the wheel to highlight RESET and then press the ENTER key.

Performing the verification test procedures

The following topics provides a summary of the procedures, as well as items to take into
consideration before performing any verification test.

WARNING
10-4
Reading limits = 10.03k  [(10.03k x 60ppm) + (10.03k x 6ppm)]
Reading limits = 10.03k  [(0.000618) + (0.0000618)]
Reading limits = 10.03k ± 0.0006798
Reading limits = 10.0293202k to 10.0306798k

The Input/Output terminals of the DMM and switch cards are rated for
connection to circuits rated Installation Category I only, with transients
rated less than 1500V peak. Do not connect the DMM or switch card
terminals to CAT II, CAT III, or CAT IV circuits.
