ANENG ST170 Mini Digital Clamp-On Multimeter

1. SAFETY INFORMATION

This Mini-sized digital clamp multimeter has been designed according to IEC61010 oncoming electronic measuring instruments with an over voltage category (CAT II 600V) and Pollution degree 2.

A WARNING

To avoid possible electric shock or personal injury, follow these guidelines:

1. Do not use the meter if it is damaged. Before you use the meter, inspect the case. Pay particular attention to the insulation surrounding the connectors.
2. Inspect the test leads for damaged insulation or exposed metal. Check the test leads for continuity. Replace damaged test leads before you use the meter.
3. Do not use the meter if it operates abnormally. Protection may be impaired. When in doubt, have the meter serviced.
4. Do not operate the meter around explosive gas, vapor, or dust.
5. Do not apply more than the rated voltage, as marked on the meter, between terminals, or between any terminal and earth ground.
6. Before use, verify the meter's operation by measuring a known voltage.
7. When measuring current, turn off circuit power before connecting the meter in the circuit.
8. When servicing the meter, use only specified replacement parts. Use with caution when working above 30V ac rms, 42V peak, or 60 dc. Such voltages pose a shock hazard.
9. When using the probes, keep your fingers behind the finger guards on the probes.
10. Connect the common test lead before you connect the live test lead. When you disconnect test leads, disconnect the live test lead first.
11. Remove the test leads from the meter before you open the battery door.
12. Do not operate the meter with the battery door or portions of the cover removed or loosened.
13. To avoid false readings, which could lead to possible electric shock or personal injury, replace the batteries as soon as the low battery indicator ( "-" ) appears.
14. CAT II - Measurement Category II is for measurements performed on circuits directly connected to low voltage installation. (Examples are measurements on household appliances, portable tools and similar equipments.) Do not use the meter for measurements within Measurement Categories II or IV.

7. CONTROL BUTTON DESCRIPTION

7-1. HOLD AND BACKLIT BUTTON(HOLD/ ? )

1. When you press this button briefly, LCD will show the last reading, and "H" symbol will appear till pushed again. Data holding will be cancelled automatically when the function switch is rotated.
2. When you hold this button down for about 2 seconds. Turn on the headlight and press this button again for 2 seconds to turn it off.

7-2 Function select button(SELECT)

1. This key is used to switch between ( ▶ ) and AC/DC Voltage.

8. OPERATION INSTRUCTION

8-1. AC/DC VOLATAGE MEASUREMENT

1. Connect the BLACK test lead to the COM jack and the RED to the V/Ω jack.
2. Set the function switch at 20V or 600V position, Select DCV or ACV by the "SELECT" key. connect testleads across the source or load under measurement.
3. Read LCD display. The polarity of RED test lead will be indicated when making a DC measurement.

8-2. RESISTANCE MEASUREMENT

1. Connect the BLACK test lead to the COM jack and the RED to the V/Ω jack. (NOTE: The polarity of the RED lead is positive "+", and the BLACK is negative "-" ).
2. Set the function switch at "200kΩ" or "20MΩ" position.
3. Connect test leads across the resistance under measurement, and then get the test readings on LCD.

NOTE:

1. For resistance above 2 MΩ or 4MΩ, the meter may take a few seconds to stabilize reading. This is normal for high resistance measuring.
2. When the input is not connected, i.e. at open circuit, the figure "OL" will be displayed under over- range condition.
3. When check in circuit resistance, be sure the circuit under test, has all power removed and all capacitors are fully discharged.

8-3. AC CURRENT MEASUREMENT

1. Set Function/Range Switch to the AC range(s).
2. Press the trigger to open the transformer jaws. And clamp one conductor only it is impossible to make measurements when two or three conductors are clamped at the same time.
3. Display reading is showing the conductor AC current.

8-4. AUDIBLE CONTINUITY/DIODE TEST

1. Connect the BLACK test lead to the COM jack and the RED to the V/Ω jack.
2. Set the function switch at ⚡ position and push the button "SELECT" to select continuity or diode test mode. Then the symbol ⚡ or ⚡ is shown on LCD.
3. In continuity test, if the circuit resistance under test is lower than 50 Ω, built-in buzzer will sound.
4. If diode test mode is selected, connect the RED and BLACK test leads to anode and cathodes of the diode under test separately. The forward voltage drop of diode will be displayed.

8-5. CAPACITANCE MEASUREMENT

1. Connect the BLACK test lead to the COM jack and the RED test lead to the V/Ω jack. ( Note: The polarity of the RED test lead is"+")
2. Put the range selector at "200uF" position, and connect the test leads across the Capacitor under measurement. Disconnect the capacitor with the outer power source.
3. Take the reading from LCD. When test the large capacitor, it's normal to take more time for getting the values on LCD.

NOTE: Make sure of discharging all the capacitor's electricity completely before measurements.

8-6. Non-Contact AC VOLTAGE Detection (NCV)(only 6233)

1. Set the function range switch at the NCV position. Then the NCV indicating LED light is flashing.
2. Take the clamp jaw close to the AC signal.
3. Then the NCV indicating LED is constantly flash and the Beeper sounding at the same time.once ACV> 100V.

NOTE: Don't try to contact the testing place with this tester. No display on LCD at this range.

9. BATTERY REPLACEMENT

If the sign "-"" appears on the display, it indicates battery should be replaced. Remove screws and open the back case, replace the exhausted batteries with new ones (AAA 1.5V *2pc or equivalent).
