Document Number: 3700S-901-01 Rev. A / August 2007
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 r
4ppm of range), the calculated reading limits are:
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
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.

If the Series 3700 is not within specifications and not under warranty, calibrate the unit.
Test considerations
WARNING
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.
