Before operating your multimeter, become familiar with each control. A clear understanding of how your multimeter works will help to avoid mistakes and minimize measurement errors, instrument damage and the possibility of injury.

The following section describes the functions of your multimeter (see illustration).

1. Function/Range Switch - rotary control located in the center of your multimeter, used to select the function, as well as the desired range.

2. Display - color-coded pointer scales with mirrored back. Includes: OHM (Q),

AC/DC, AC 10V and battery testing scales.

3. Positive Jack - plug-in connection for red (positive) test lead.

4. Negative Jack - plug-in connection for black (negative) test lead.

5. Zero Q Adjustment Switch - Stabilizes the pointer to "0" when making

Q measurements.

DC CURRENT MEASUREMENT (DC A)

1. Connect the red test lead to the "positive" jack and the black test lead to the "negative' jack.

2. Set the Function/Range switch to the 250 mA DC A position.

3. Remove power from the circuit being measured and then open up the circuit at the point where you wish to measure the current.

4. Touch the black test prod to the 'negative" side of the circuit and the red test

prod to the "positive' side of the circuit.

Dimensions: 105 mm x 64 mm x 35 mm

it, exposing the battery compartment. Install or replace one 1.5 V "AAA" cell battery and reattach the back securely.

To replace a fuse, remove the back cover, exposing the burnt-out fuse. Replace old fuse with a 0.5 A 250 V type 5o x 20 mm fuse. Reattach back cover securely.

2. Set the Function/Range switch to the desired AC V position.

3. Touch the test prods to the circuit or device being measured, and read the voltage value on the black AC/DC voltage scale. If you are operating on the

10 V AC range, read the voltage on the red 10 V AC scale.

turning the Function/Range switch. For accurate readings, keep your multimeter

2. Set the Function/Range switch to the x 10 ii position. To ensure the dial

laying flat on a non-metallic surface and look at the scale from the point of view

where the pointer and its reflection on the mirror come together. For best results,

use a range selection in which the dial pointer is in the upper 1/3 of the multimeter scale. Before testing, ensure that the dial pointer rests directly over the "0" at the left side of the scale. Use the screw in the lower center of the multimeter face to bring the dial pointer to "0." To avoid battery drain, set Function/Range switch to "OFF" when not in use.

WARNING: To avoid electrical shock and/or damage to your multimeter, do not measure

voltage that exceeds 500 DC V or 500 AC V peak above earth ground. Before using your multimeter, inspect leads, connectors and prods for cracks or breaks.

DC VOLTAGE MEASUREMENT (DCV)

1. Connect the red test lead to the "positive' jack and the black test lead to the "negative" jack.

2. Set the Function/Range switch to the desired DC V position. If the magnitude of value is unknown, set the Function/Range switch to the highest range and reduce until desired reading is obtained.

pointer is set to "O' on the top OHM (green) scale, touch the test prods together

and use the zero Q ADJ switch until the pointer stabilizes at 'O'.

3. If the resistance being measured is connected to a circuit, turn the power off and discharge all capacitors before attaching the test prods.

4. Touch the test prods across the circuit being measured, and read the resistance value on the green OHM scale. Multiply the reading by 1000,100 or 10, depending on the range you are using.

BAHERY TEST

1. Connect the red test lead to the "positive" jack and the black test lead to the

"negative' jack.

2. Set the Function/Range switch to the type of battery to be tested.

3. Touch the red test prod to the (+) terminal of the battery and the black test prod to the (-) terminal and read the result on the BAT scale. If the pointer is in the red "replace" zone, the battery needs to be replaced. If the pointer is in the green "good" zone, the battery is charged. If the pointer is in the white zone, the

battery power is low and should be replaced.
