Safety Information
/K Safety Information (See Users Manual for complete information.)
•Before you use the calibrator, inspect the insulating cover. Look for cracks
or missing plastic. Pay particular attention to the insulation surrounding the
connectors. Do not use the calibrator if it is damaged.
•Disconnect the power and discharge all high-voltage capacitors in the
equipment under test before testing resistance or continuity.
•Inspect the test leads for damaged insulation or exposed metal. Check test
lead continuity. Replace damaged test leads.
•Do not use the calibrator if it looks damaged or if it operates abnormally.
Protection may be impaired. When in doubt, have the calibrator serviced.
•Select the proper function and range for your measurement.
•Use caution when working above 42V dc or 25Vac rms. Such voltages pose
ashock hazard.
•When using the probes, keep your fingers away from the probe contacts.
Keep your fingers behind the finger guards on the probes.
•Connect the common test lead before you connect the live test lead. When
you disconnect test leads, disconnect the live test lead first.
•Do not operate the calibrator around explosive gas, vapor, or dust.
•When using apressure module, make sure the process pressure line is shut
off and depressurized before you connect it to the pressure module.
•Disconnect test leads before changing to another measure or source
function.
•Designed and tested in accordance with IEC-1 01 0-1. Use the calibrator only
as specified in this Guide or the Users Manual; otherwise the protection
provided by the calibrator may be impaired.
•When servicing use only specified replacement parts.
International Electrical Symbols
MCalibrator is protected throughout by double insulation or reinforced
insulation.
/j\ Caution! Refer to this manual before using the Calibrator.
CAT II Overvoltage (Installation) Category II per IEC 1010-1 refers to the
level of Impulse Withstand Voltage protection provided. Typical
locations include; Mains Wall outlets, local appliances and POR-
TABLE EQUIPMENT.

Using Your 701/702 Quick Reference Guide
This Quick Reference Guide to the Mode! 701 and 702 Documenting Process
Calibrators describes how to do the following:
•Make measurements using MEASURE mode.
•Simulate input signals using SOURCE mode.
•Calibrate an instrument using simultaneous MEASURE/SOURCE mode.
•Store data.
•Use the internal current loop supply.
•Change various lSETHparameters,
The 701 and 702 have many more features. Refer to the Users Manual for the
ramp, trip detect, and data logging functions. Refer to the PMLink™ manual for
how to interface the 702 with aPC.

Introduction
Charging the Battery and Battery Life
When the Oannunciator appears, stop using the calibrator and charge the
battery. For longest battery life, wait for the E3 annunciatorto appear before you
charge the battery. When battery save is enabled, the [Sa} indicator shows in
reverse video. See the battery save feature on page 27.
