Quick start...

Clamp the jaws around a single

conductor, set the meter to the

lowest mVAC range and read

amps up to "199.9".

Introduction...Introduction...

Introduction...

The Fieldpiece Model ACH

converts AC current to a voltage

easily measured by most DMM's

by just clamping the jaws around a

current carrying conductor.

The model ACH1 current

clamp converts AC amps to

voltage at a rate of 1 amp to 1mV

(1000 to 1).

The ACH Clamp Head was

designed to be snapped directly

onto the Fieldpiece HS Series

DMM or to be used with the

Fieldpiece HB70 series or any

DMM that has the industry

standard "Fluke" style input jacks

using the Deluxe Test Leads

(ADL2).

When snapped onto the

Fieldpiece HS Series Stick Style

DMM the pair make a convenient

one piece digital clamp meter that

reads current directly, without

requiring the user to perform

mental calculations or move the

decimal point.

The ACH also snaps onto the

EHDL1 electronic handle to make

a convenient stand alone current

clamp meter.

For your safety...For your safety...

For your safety...

Do not attempt to measure any

circuit in which the circuit-to-

ground voltage exceeds 1000V

rms.

Measurement of AC power

sources with inductive loads or AC

power sources during electrical

storms may result in extremely

high-voltage, high-energy transients

that could damage the meter and

consequently expose the user to a

dangerous shock hazard.

Inspect the test leads for

damage to the insulation or exposed

metal. Replace or do not use if

suspect.

When disconnecting from a

voltage measurement, disconnect

the “hot” lead first, then the

common.

Discharge capacitors prior to

making resistance or capacitance

measurements.

Work with others.

Use one hand.Hands, shoes, and

floor must be dry when taking

measurements.

Avoid use of the current

converter under humid or damp

conditions which could affect the

dielectric withstanding voltage of

the clamp.

Operating instructions:Operating instructions:

Operating instructions:

1. Connect the ACH Clamp Head

to digital multimeter V- W and

COM terminals. (Polarity is

not important.)

2. Set the multimeter to mVAC

range.

3. Snap the jaws of the current

converter around one of the

current-carrying conductors.

Make sure the jaws are tightly

clamped.

4. Directly read the current value

(in amperes) indicated on the

display (multiply by 1000 if

using the 2V range).

5. If meter dispalays overload,

change range to next highest

(2000mVAC or 2VAC. For

2VAC range, multiply reading

by 1000.)

Maintenance:Maintenance:

Maintenance:

For the Clamp Head to operate

properly, the magnetic joint

surfaces should be maintained free

of dust, dirt, or residues of wire

insulation.

Clean the Clamp Head using a

mild detergent in water. Other

solvents may damage the plastic or

reduce the effectiveness of the

insulation. Dry the instrument

thoroughly before use.
