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

The step by step procedures in this guide use the following conventions:

Softkey labels are shown in boldface type. For example, Scale %means press the

Scale %softkey.

Keycap pictures mean press the keys shown in the sequence shown.

For example, [~™a]©@ 1enter |means press the key followed by (D,

and so on. CSDCS!) means press the GSII key twice.

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.

2Cycles the calibrator through MEASURE, SOURCE, and MEASURE/SOURCE

modes.

3Selects mA (current) measure or source function. For loop power on/off, go

to the iSETUPimode.

4Enter and exit the mode to modify operating parameters.

5Perform the function defined by the label above each key on the display.

6Turns the backlight on and off.

7Selects the pressure measurement function.

8Selects TC (thermocouple) or RTD (resistance temperature detector) mea-

surement or sourcing functions.

ntroduction

9Toggles between autorange and locked range in MEASURE mode, and

increments range. Each time you press lSANatl,the calibrator locks on the next

higher range. Press this key again for 2seconds to resume autorange.

10Clears apartial data entry or zeros the output when in the SOURCE mode.

11 Use to adjust the display contrast. Also, use to make selections when

prompted. These keys also increment or decrement the sourced output in

steps.

12 Terminates anumeric entry when setting asource value, or selects entries

from lists.

13 Toggles between resistance and continuity functions in MEASURE mode, or

selects the resistance function in SOURCE mode.

14Use whenever anumeric entry is required.

15 Toggles between ac voltage and frequency functions in the MEASURE mode,

or selects frequency output in the SOURCE mode.

16Selects the dc voltage function in the MEASURE mode, or selects dc voltage

in the SOURCE mode.
