Safety

This symbol adjacent to another symbol, terminal or operating device indicates that

the operator must refer to an explanation in the Operating Instructions to avoid

personal injury or damage to the meter.

This WARNING symbol indicates a potentially hazardous situation, which if not

avoided, could result in death or serious injury.

This CAUTION symbol indicates a potentially hazardous situation, which if not

avoided, may result damage to the product.

This symbol advises the user that the terminal(s) so marked must not be connected

to a circuit point at which the voltage with respect to earth ground exceeds (in this

case) 1000 VAC or VDC.

This symbol adjacent to one or more terminals identifies them as being associated

with ranges that may, in normal use, be subjected to particularly hazardous

voltages. For maximum safety, the meter and its test leads should not be handled

when these terminals are energized.

This symbol indicates that a device is protected throughout by double insulation or

reinforced insulation.

Operating Instructions

WARNING: Risk of electrocution. High-voltage circuits, both AC and DC, are very dangerous

and should be measured with great care.

1. ALWAYS turn the function switch to the OFF position when the meter is not in use.

2. If “OL”appears in the display during a measurement, the value exceeds the range you

NOTE: The conductors in electrical cord sets are often twisted. For best results, rub the probe

tip along a length of the cord to assure placing the tip in close proximity to the live

conductor.

NOTE: The detector is designed with high sensitivity. Static electricity or other sources of

energy may randomly trip the sensor. This is normal operation

AUTORANGING/MANUAL RANGE SELECTION

When the meter is first turned on, it automatically goes into AutoRanging. This automatically

selects the best range for the measurements being made and is generally the best mode for

most measurements. For measurement situations requiring that a range be manually selected,

perform the following:

1. Press the RANGE key. The “AUTO” display indicator will turn off.

2. Press the RANGE key to step through the available ranges until you select the range you

want.

3. To exit the Manual Ranging mode and return to Autoranging, press and hold the RANGE

key for 2 seconds.

Note: Manual ranging does not apply for the Temperature functions.

MAX/MIN

1. Press the MAX/MIN key to activate the MAX/MIN recording mode. The display icon

"MAX" will appear. The meter will display and hold the maximum reading and will update only

when a new “max” occurs.

2. Press the MAX/MIN key again and the display icon "MIN" will appear. The meter will

display and hold the minimum reading and will update only when a new “min” occurs.

3. To exit MAX/MIN mode press and hold the MAX/MIN key for 2 seconds.

RELATIVE MODE

The relative measurement feature allows you to make measurements relative to a stored

reference value. A reference voltage, current, etc. can be stored and measurements made in

comparison to that value. The displayed value is the difference between the reference value

and the measured value. Note: Relative mode does not operate in the 4-20mA function.

1. Perform the measurement as described in the operating instructions.

WARNING: Risk of Electrocution. Before use, always test

the Voltage Detector on a known live circuit to verify proper

operation

2. Press the REL button to store the reading in the display and the "REL" indicator will appear

on the display.

3. The display will now indicate the difference between the stored value and the measured

value.

4. Press the REL button to exit the relative mode.
