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.

WARNING

This WARNING symbol indicates a potentially hazardous situation, which if not avoided, could result in death or serious injury.

CAUTION

MAX

600V

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) 600 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.

CAUTIONS

 Improper use of this meter can cause damage, shock, injury or death. Read and understand this user manual before operating the meter.

 Always remove the test leads before replacing the battery or fuses.

 Inspect the condition of the test leads and the meter itself for any damage before operating the meter.

 Use great care when making measurements if the voltages are greater than 25 VAC rms or 35

VDC. These voltages are considered a shock hazard.

 Warning! This is a Class A device. This device can cause interference in residential areas.

 Always discharge capacitors and remove power from the device under test before performing

Diode, Resistance or Continuity tests.

 Voltage checks on electrical outlets can be difficult and misleading because of the uncertainty of connection to the recessed electrical contacts. Other means should be used to ensure that the terminals are not "live".

 If the equipment is used in a manner not specified by the manufacturer, the protection provided by the equipment may be impaired.

 This device must not be used by children. It contains hazardous objects as well as small parts that the children could swallow.

 Do not leave batteries and packing material lying around unattended; they can be dangerous to children.

 In the event that this device will be stored for an extended period of time, remove the batteries.

 Expired or damaged batteries can leak and can be hazardous to skin. Use suitable hand gloves in such cases.

 Do not short-circuit the battery. Do not place the battery near a fire.

 Never mix battery types. Always install new batteries of the same type.

SAFETY INSTRUCTIONS

This meter has been designed for safe use, but must be operated with caution. The rules listed below must be carefully followed for safe operation.

1. NEVER apply voltage or current to the meter that exceeds the specified maximum:

Input Protection Limits

V AC/DC, Resistance, Diode Test, Continuity

μA or mA AC/DC

A AC/DC

2. USE EXTREME CAUTION when working with high voltages.

600 VDC/AC rms

IR Measurement Notes

1. The object under test should be larger than the spot (target) size calculated by the field of view diagram.

2. If the surface of the object under test is covered with frost, oil, grime, etc., clean before taking measurements.

3. If an object's surface is highly reflective, apply masking tape or flat black paint to the surface before measuring.

4. The meter will not make measurements through glass steam, dust, and smoke.

5. To find a hot spot, aim the meter outside the area of interest then scan across (in an up and down motion) until the hot spot is located.

Maintenance

WARNING: To avoid electric shock, disconnect the test leads from any source of voltage before removing the back cover or the battery or fuse covers.

WARNING: To avoid electric shock, do not operate the meter until the battery and fuse covers are in place and fastened securely.

This MultiMeter is designed to provide years of dependable service, if the following care instructions are followed:

1. KEEP THE METER DRY. If it gets wet, wipe it off.

2. USE AND STORE THE METER IN NORMAL TEMPERATURES. Temperature extremes can shorten the life of the electronic parts and distort or melt plastic parts.

3. HANDLE THE METER GENTLY AND CAREFULLY. Dropping it can damage the electronic parts or the case.

4. KEEP THE METER CLEAN. Wipe the case occasionally with a damp cloth. DO NOT use chemicals, cleaning solvents, or detergents.

5. USE ONLY FRESH BATTERIES OF THE RECOMMENDED SIZE AND TYPE. Remove old or weak batteries so they do not leak and damage the unit.

6. IF THE METER IS TO BE STORED FOR A LONG PERIOD OF TIME, the batteries should be removed to prevent damage to the unit.

BATTERY and FUSE Replacement

WARNING: To avoid electric shock, disconnect the test leads from any source of voltage before removing the battery cover.

1. Turn power off and disconnect the test leads from the meter.

2. Lift the meter stand to expose the battery cover.

3. Open the rear battery/fuse compartment by removing the Phillips head screw on the lower rear of the meter.

4. Carefully pull down on the cover just enough to release the latch and then lift it off. The cover will not pull down all the way.

5. Remove the old battery or fuse and install a new one of the correct rating.

6. Place the battery/fuse cover back in place. Secure with the screw.

WARNING: To avoid electric shock, do not operate the meter until the battery cover is in place and fastened securely.

NOTE: If the meter does not work properly, check the fuses and replace the battery to make sure that they are still good and that they are properly inserted.

Battery Safety Reminders o Please dispose of batteries responsibly; observe local, state, and national regulations. o Never dispose of batteries in a fire; batteries may explode or leak. o Never mix battery types; install new batteries of the same type.
