Frequently Asked Questions - 3166 Kyoritsu

How do I measure AC voltage with the Kyoritsu 3166?

Set the rotary switch to the AC voltage range (V~). Connect the black test lead to the COM jack and the red lead to the VΩ jack. Touch the probes to the circuit and read the display.

How do I replace the battery?

Turn off the meter and remove the test leads. Unscrew the battery cover on the back, remove the old 9V battery, and insert a new one. Reattach the cover.

What is the maximum voltage I can measure?

The Kyoritsu 3166 can measure up to 600V AC/DC. Exceeding this may damage the meter or cause injury.

How do I test continuity?

Set the rotary switch to the continuity/beep symbol (usually a diode or sound wave). Insert the test leads as for resistance. The meter will beep if resistance is below a threshold.

What do the symbols on the dial mean?

V~ is AC voltage, V- is DC voltage, A~ is AC current, A- is DC current, Ω is resistance, Hz is frequency, and the diode/beep symbol is for diode and continuity tests.

Is the Kyoritsu 3166 safe for use on mains circuits?

Yes, it has a safety rating of CAT III 600V and CAT II 1000V, making it suitable for most household and industrial mains measurements.

How do I measure current?

Set the dial to the appropriate current range (A~ or A-). Move the red lead to the 10A jack for high current or mA jack for low current. Break the circuit and connect the meter in series.

What does the 'HOLD' button do?

Press 'HOLD' to freeze the current reading on the display. Press again to release. This is useful for capturing measurements in hard-to-see places.

How do I measure resistance?

Set the dial to Ω. Ensure the circuit is de-energized. Connect the test leads across the component. Read the resistance value on the display.

Why does my meter show 'OL'?

'OL' means overload or open loop. The measured value exceeds the selected range, or the circuit is open. Select a higher range if possible.

4-3 Insulation Resistance Measurement

⚠ WARNING

To avoid electrical shock, do not touch the test lead tips and the circuit under test during measurement.

CAUTION

To avoid damage to the instrument, insulation measurement must be performed on de-energized circuits only. Make sure that the circuits or equipment is disconnected before proceeding with an insulation test.

(1) Connect the test leads to the instrument and the circuit under test.

(2) Check the circuit under test is not energized as follows. Connect the test leads to the circuit under test and read a voltage value. If the circuit is live, the meter indicates the voltage. If the meter indicates 0V, the circuit is dead.
(3) Press test button. Read the red megaohm scale directly. ● Continuous Measurement
A lock down feature is incorporated on the test button. Pressing and turning it clockwise lock the test button in the continuous operating position.

1. Always make sure to insert the plug of test leads fully into the terminal of the instrument
2. Never exceed the maximum allowable input of any measuring range when making measurement.
3. Make sure to never apply a voltage more than 600V AC or DC between the terminal of the instrument and earth.
4. Never try to operate the instrument in an explosive atmosphere (i.e. in the presence of flammable gases or fumes, vapor or dust).
5. Always inspect the instrument, test leads and accessories for any sign of damage or abnormality before every use. If abnormal conditions exist (e.g. broken test leads, cracked enclosure of the instrument), do not try to make measurements.
6. Do not push the test button or lock it down while connecting test leads.
7. Do not touch the circuit under test during insulation testing.
8. Make sure to remove the test lead from the instrument and turn the power off before opening the battery compartment cover for battery replacement.
9. Always turn the power off after use.
10. Do not expose the instrument to the direct sun, dew fall, or extreme temperatures.
11. Do not expose the instrument to a temperature of more than 50°C.
12. Calibration and repair of any instrument should only be performed by qualified and trained service technicians.
13. Do not install substitute parts or perform any unauthorized modification of the instrument. Return the instrument to your distributor for service and repair to ensure that safety features are maintained.
14. The instrument must be used by a competent, trained person and operated in strict accordance with the instructions. KYORITSU will not accept liability for any damage or injury caused by misuse or noncompliance with the instructions or safety procedures. It is essential to read and understand the safety rules contained in the instructions. They must be observed when using the instrument.

2. Features

● AC voltage measurement can be made without depressing the test button.

● Battery check facility

● Uses only 4×1.5V battery type R6, AA or equivalent.

3. Specifications

● Measuring ranges accuracy(at 23±5°C, relative humidity 45-75%)

To release the lock turn the test button counter clockwise.

Never leave the test button locked down when not in use.

(4) Discharging capacitance of circuit under test. It is possible that capacitance has been stored in the circuit under test after insulation testing. To discharge the e circuit capacitance reverse the connection of the earth clip and line probe. Remaining electric charges can be observed on AC voltage warning range.

⚠ WARNING

Do not touch the circuit under test immediately after testing. Capacitance stored in the circuit may cause electric shock.

5. Battery Replacement

⚠ WARNING

To avoid shock hazard disconnect the test leads from the instrument.

To replace the batteries, first disconnect all test leads from the instrument. Open the battery compartment cover by unscrewing the metal captive screw to reveal battery compartment. The four 1.5V SUM-3(R6)type batteries are located in a compartment. Always replace all four batteries with new ones at the same time. Never mix old and new ones. Screw the battery compartment lid back on before using the instrument.
