DCM97K -- Separable Meter :

Digital Multimeter (DMM) & AC Current Transducer

1. INTRODUCTION

Thank you for buying the DCM97K ! We
are confident that this multifunctional
device will serve you well for many
years to come.

This is a separable meter consisting of
a digital multimeter (DMM) and an AC
current transducer. The DMM can be
used individually for DC & AC voltage
measurements and for measuring
resistance, diodes and continuity. The
meter can be used to measure AC
currents when the AC current
transducer is mounted firmly on the
DMM.

The multimeter has been designed in
accordance with IEC-1010 concerning
safety requirements for electrical
measuring instruments and hand-held
current clamps.

See figure 1.

1. SAFETY INFORMATION

This multimeter has been designed in accordance with UL1244 and IEC-1010
concerning safety requirements for electronic measuring instruments with an
overvoltage category (CAT II) and pollution 2.
Follow all safety and operating instructions to ensure that the meter is used safely
and is kept in good working order.

1.1. Preliminary
The user should observe all standard safety rules :

l Do not abuse the device.
l Full compliance with safety standards can be guaranteed only if the device is

used with the supplied test leads. If necessary, they should be replaced with
identical leads or leads with identical electronic ratings. All measuring leads
should be in good condition.

1.2. Use

l Observe a warm-up delay of at least 60 seconds.
l The display may become unstable and the readings inaccurate if the multimeter

is used in the vicinity of noise-generating equipment.

l Never exceed the limit values of the various measurement ranges as indicated

in this manual.

l Disconnect all test leads from circuits that are currently being tested before

selecting a different function.

l Never perform resistance measurements on live circuits.
l Always be careful when working with voltages in excess of 60VDC or 30Vrms

AC.

l Keep your fingers behind the probe barriers while using the device.
