Return your analogue insulation tester to your nearest distributor for service.
• Never replace the protective fuse with any other than the specified or approved equivalent.
• Your analogue insulation tester has been designed with your safety in mind. However, no design can completely protect against incorrect use. Electrical circuits can be dangerous and / or lethal when a lack of caution or poor safety practice is used. Use caution in the presence of voltage above 24V as these pose a chock hazard.
• Pay attention to cautions and warnings which will inform you of potentially dangerous procedures.
• Your analogue isolation tester has a live circuit warning beeper. If it is connected to an AC live circuit, a beep of twice the frequency of the voltage present will be heard.
• DOT NOT proceed to test and immediately disconnect the instrument from the circuit. In addition, the warning light will lit if the voltage is above 100V DC or 70VAC. When AC voltage is present, before testing, it’s value is displayed on the AC scale.
• Do not exceed the maximum permissible input ratings (danger of serious injury and/or destruction of the equipment).
• Replace a defective fuse only with a fuse of the original rating. Never short-circuit fuse or fuse holding.
• Disconnect test leads or probe from the measuring circuit before switching modes or functions.
• To avoid electric shock, disconnect power to the unit under test and discharge all capacitors before taking any resistance measurements.
• To avoid electric shock, do not operate this product in wet or damp conditions. Conduct measuring works only in dry clothing and rubber shoes, i. e. on isolating mats.
• Never touch the tips of the test leads or probe.
• Comply with the warning labels and other info on the equipment.
• Always start with the highest measuring range when measuring unknown values.
• Do not subject the equipment to direct sunlight or extreme temperatures, humidity or dampness.
• Do not subject the equipment to shocks or strong vibrations.
• Do not operate the equipment near strong magnetic fields(motors, transformers etc.).
• Keep hot soldering irons or guns away from the equipment.
• Allow the equipment to stabilize at room temperature before taking up measurement (important for exact measurements).
• Do not turn the rotary function switch during voltagemeasurement, otherwise the meter could be damaged.
• Use caution when working with voltages above 35V DC or 25V AC. These Voltages pose shock hazard.
• Replace the battery as soon as the battery indicator “BAT” appears. With a low battery, the meter might produce false reading that can lead to electric shock and personal injury.
• Fetch out the battery when the meter will not be used for long period.
• Periodically wipe the cabinet with a damp cloth and mid detergent. Do not use abrasives or solvents.
• The meter is suitable for indoor use only

Precautions & Preparation for Measurements

1. Remove the power from the circuit when making the measurement. If any voltage is present in the testing circuit, then it could damage the units.
2. Ensure, that the batteries (8 x 1,5 V AA battery) are connected correctly to the right position into the battery compartment.
3. Rotate the “Function-/Selector” to the right position before making measurement.

Measuring Procedure

5.1. Functions
5.1.1. Battery Check

• Turn the function selector to Battery Check.
• This function has a load which draw about 205mA when test is performed, and therefore it is doing a worst case battery test.
• Then press the test button, the pointer should be in the BAT.OK area.
• During the test, the BAT.OK lead (on line battery check) must lit if the pointer is in the BAT.OK area.

5.1.2. DC Warning
The DC warning buzzer will beep continuously when DC voltage is higher than 30 VDC on the test probes and the test button is not pressed. The neon light “circuit live” will lit when the voltage on the test probes is higher than 90 VDC and the test button is not pressed.
5.1.3. AC Warning
The AC warning buzzer will beep continuously when AC voltage is higher than 20VAC on the test probes and the test button is not pressed. The neon light “circuit live” will lit when the voltage on the test probes is higher than 65VDC and the test button is not pressed.
5.1.4. AC Measurement
The AC measurement is automatic on this instrument. As soon as AC voltage is present on the test leads, the instrument will display the AC voltage from 20 to 600 VAC on the linear scale.
5.1.5. Low Ohms Measurement 0-3Ω/500Ω
Always check for voltage before testing and measuring on a circuit. This instrument is intended for measuring low Ω and Insulation resistance on un- energized circuits only.
The first procedure to follow, is to zero the test leads and the fuse resistance. The instrument is equipped with a zero Ω Knob. First, short circuit the test leads by connecting them together, then press the test button and adjust the zero Ω knob until the pointer is precisely on the “=” of the 3Ω/500Ω scale.
Use the mirror scale to be precise with the pointer. connect the test leads to the circuit to be measured. For short test, press button and keep pressed. For long test or hand free measurements, press and turn the test button.

5.1.6. Insulation Resistance Measurement at 250VDC
Always check for voltage before testing and measuring on a circuit.
This instrument is intended for measuring low Ω and Insulation resistance on un-energized circuits only.
Check the test leads and fuse resistance by zeroing the test leads and fuse. Connect the test leads to the circuit to be measured and wait for a few seconds. The instrument will automatically discharge any remaining energy which could be present on the circuit and will check for voltage at the same time.
Once you are sure that the circuit to be tested is not energized, then press the button for a short test duration or press and turn the button for a long test. Once your end the test , allow a few seconds for the Instrument to automatically discharge the circuit

Battery & Fuse Replacement

6.1. Battery Replacement
Your Analogue insulation tester’s battery is situated under the tester. The BAT.OK will not lit when battery need to be replaced.
