ACROSS a voltage source. Check fuse first.

•

Never replace a fuse with one of a different rating.

•

Do not operate instrument in an explosive atmosphere (flammable gases, fumes,

vapor, dust.)

•

Do not use this or any piece of test equipment without proper training

•

CRT SERVICE SAFETY REMINDER: A potential danger exists when measuring voltages in

the horizontal output and damper stages of CRT equipment. (High voltage transients greater

than 8000 V). Refer to your CRT service manual for proper servicing instructions.

Instrument Familiarization

Your shipping carton should include the multimeter, a holster with Magne-Grip hanging strap, one test

lead set (one black, one red) threaded alligator clips, one 9 V battery (installed), one 2 mm hex wrench

(inside holster) and this manual. If any of the items are damaged or missing, immediately return the

complete package to the place of purchase for an exchange.

Protective Holster

The holster/tilt stand protects the meter form accidental falls and provides greater ease of use. Both test

lead probes can be attached to the holster for storage. One probe can be attached for measurement,

holding the meter with probe in one hand and the second probe in the other hand.

Overload Indication: (input exceeds meter's highest range) and Display Overload (input

exceeds selected range) are both signaled by a 1 displayed on the left side of the LCD.

In the volts or amperage ranges Display Overload can be corrected by selecting a

higher range to display the input reading. If the highest range is selected and the overload indication

continues, this is now an Input Overload. Remove the test leads from the circuit immediately as input

exceeds the meter's rated capability.

Note: In both instances, the overload indication is normal in the OHMS and Continuity/Diode ranges to

indicate an open circuit. Function Error is signaled a by continuous tone when a test lead is placed in

either the 2 A jack and the selector switch is not in the correct current range. If the meter is connected

to a voltage source with test leads set for current, very high current could result. All current ranges are

protected with fast acting fuses.

Battery Low: When the battery low indicator is displayed the battery has less than 50 hours operation

and the accuracy of the meter can no longer be guaranteed.

Turn the meter on by turning the function/range switch away from OFF and selecting the parameter

you want to measure. If the parameter selected has more than one range position, the display will

indicate the range by a changing position of the decimal point. Always select the highest range if the

maximum potential reading is not known. Then turn the selector switch down in range to obtain the

best resolution reading.

When connecting or disconnecting test leads to a circuit, always turn off power to device or

circuit being tested and discharge all capacitors.

Strictly observe the max input limits.

Do not change functions while test leads are connected to circuit.
