DCM300E Earth Leakage Clamp Meter

Safety Warnings

■ Do not take measurements beyond maximum selected range.

■ Take extreme care and keep hands behind the hand guard when

taking measurements above 30 V RMS.

■ Do not operate the instrument with the battery cover removed.

Do not operate the instrument if any part of it is damaged.

■ Do not operate the instrument in environments subject to high

temperature, damp, humidity or excessive vibration.

■ Safety Warnings must be read and understood before the

instrument is used, and observed during use.

Note: The instrument must only be used by suitably

trained and competent persons

General Description

The DCM300E is a rugged lightweight pocket size clamp meter designed to

measure a.c. earth leakage currents. This enables earth leakage faults to be

detected and located without having to isolate and disconnect circuit wiring.

Additionally, the DCM300E measures a.c. circuit currents up to 300 Amps.

of microprocessor technology and features a clear 31⁄2 digit LCD combining

digital and bar-graph analogue readings.

The two position mode switch provides 4 ranges; 30 mA, 300 mA, 30 A and 300

A, with minimum resolution of 0,01 mA on the 30 mA range.

To conserve battery power, Auto shut off operates after a period of 10 minutes

of inactivity by the instrument. The instrument can be switched back on by

selecting Off and then On again.

Measurement of Leakage Current

Earth Conductors

1) Set the range selector switch to the

30 /300 mA position.

2) Set the Power switch to On.

3) Ensure that the Data hold switch is

Off. DH is not displayed.

4) Clamp the jaws around the earth

conductor.

5) If necessary, press the Data hold switch

DH is displayed.

6) Take the reading from the Digital and/

or Bar-graph display.

Single phase or 3 phase conductors

1) Set the range selector switch to the

30 /300 mA position.

2) Set the Power switch to On.

3) Ensure that the Data hold switch is

Off DH is not displayed.

4) Clamp the jaws around both the

phase and neutral conductors, or the

3 phase conductors in the case of

3 phase supplies

5) If necessary, press the Data hold switch

DH is displayed.

6) Take the reading from the Digital and/

or Bar-graph display.

Features and Controls

Measurement of Line Current

1) Set the range selector switch to the

30 /300 mA position.

2) Set the Power switch to On.

3) Ensure that the Data hold switch is Off

DH is not displayed.

4) Clamp the jaws around one

conductor of the circuit under test.

5) If necessary, press the Data hold switch

DH is displayed.

6) Take the reading from the Digital and/

or Bar-graph display.

Battery Replacement

1) When the symbol appears on

the display, the two 1,5 V button cells

must be replaced.

2) Switch the DCM300E Off.

3) Loosen the small cross head screw

securing the battery cover, and remove

the cover. Take care not to lose the

small screw.

4) Remove both exhausted cells and

carefully ﬁt two new cells into the

recess. Position both cells +ve side up.

5) Replace the battery compartment

cover and re-secure with the small

cross head.

Battery cover screw: The correct size screw must be used and ﬁtted to ensure battery cover security, and safe operation.
