temperature, frequency, etc.

DESCRIPTION

The 317 and 319 are hand-held and battery-operated clamp

meters that can measure AC current, DC current, AC voltage,

DC voltage, resistance, continuity and frequency.

The clamp meter is battery powered with a digital display.

Except where noted, the descriptions and instructions in this

datasheet apply to both the 317 and 319 clamp meters.

Warning: To avoid possible electric shock or

personal injury, read “Safety Information” before using

the clamp meter.

SAFETY INFORMATION

Use the clamp meter only as specified in this datasheet,

otherwise the protection provided by the clamp meter may be

impaired.

Adhere to local and national safety codes. Individual

protective equipment must be used to prevent shock and arc

blast injury where hazardous live conductors are exposed.

Use extreme caution when working around bare conductors

or bus bars. Contact with the conductor could result in

electric shock.

Use caution when working with voltages above 30V AC rms,

42V AC peak, or 60V DC. These voltages pose a shock

hazard.

Never measure current while the test leads are inserted into

the input jacks.

Do not use the clamp meter in wet, dirty or hazardous

environment.

Do not use the clamp meter or test leads if either appears

damaged. Inspect the clamp meter and test leads before

using. Look for cracks or missing plastic. Pay attention to

the insulation around the connectors. Do not use if

insulation is damaged or metal is exposed.

Check the test leads for continuity. Do not use the clamp

meter if test leads read open.

When using probes, keep fingers behind the finger guards.

Do not hold the clamp meter anywhere above the tactile

barrier. See figure 5.

Disconnect circuit power and discharge all high-voltage

capacitors before testing resistance, continuity, or diodes.

Check clamp meter operation on a known source before

and after use.

Use the proper terminals, function, and range for your

measurements.

Do not apply more than the rated voltage, as marked on

clamp meter, between any terminal and earth ground.

Before opening back cover to replace batteries, remove test

leads and disconnect clamp meter from any circuits being

measured. Do not operate clamp meter with cover removed

or the case open.

To avoid false readings that can lead to electrical shock or

injury, replace the batteries as soon as the low-battery

indicator ( ) appears. The clamp meter will shut down

when the batteries get low.

Have the clamp meter serviced only by qualified service

personnel.

Do not use the current sensor if the wear indicator in the

jaw opening is not visible. See figure 4.

Clamp Meter

When making current measurements, disconnect the test leads from the clamp meter.

Keep fingers behind Tactile Barrier. See table 4.

Note

When measuring current, center the conductor in the clamp using the alignment marks on the clamp. See table 4.

Zero

Before taking DC measurements, zero the clamp meter to ensure correct readings. Zeroing the clamp meter removes DC offset

(ambient noise) from the reading.

Note

Before zeroing the clamp meter, make sure the jaws are closed and there is no conductor between them.

To zero the clamp meter, press .

MEASURING AC OR DC CURRENT

To measure AC or DC current:

1. Turn the rotary function switch to the proper current range.

2. Press to select DC current if necessary. The default is AC current.

3. If measuring DC, wait for the display to stabilize and then press to zero the clamp meter.

Note: Before zeroing the clamp meter, make sure the jaws are closed and there is no conductor between them.

4. Open the clamp by pressing the jaw release and insert the conductor to be measured into the clamp.

5. Close the clamp and center the conductor using the jaw alignment marks.

6. View the reading on the LCD.

Warning: To avoid possible electric shock or personal injury, currents moving in opposite directions cancel each

other. Place only ONE conductor into the clamp at a time, see figure 5.

HOLD

To capture and hold the present reading, press while taking a reading. Press again to return to the live reading. High

voltage will be designated by .

MIN MAX AVG

To use the Min Max Avg functions:

1. Press once to set the clamp meter to MAX (maximum) mode.

2. Press again to set the clamp meter to MIN (minimum) mode.

3. Press a third time and the clamp meter displays an AVG (average) of the readings.

4. Pressing for more than 2 seconds sets the clamp meter back to normal operation.

5. Press in MIN MAX AVG mode to freeze the realtime record. In this mode, press to select a recorded value to view.

INRUSH CURRENT (319 ONLY)

To measure inrush current (see figure 10.)

1. Place the source wire into the clamp. Make sure the wire is below the alignment marks on the clamp.

2. With the source power off, turn the clamp meter to the correct range of .

3. Press .

4. Switch the source power on and note the inrush current reading on the display.
