● Never change function switches with test probe connected to the equipment under test. ● Do not install substitute parts, perform any unauthorized modification, or disassemble the instrument. Return the instrument to Kyoritsu or your distributor for service and repair so as to ensure the safety features are maintained.

5. PREPARATION FOR MEASUREMENT 5-1 Removing the Cover Model 3005A/3007A have a dedicated cover to protect against an impact from the outside and prevent the operation part, LCD, and connector socket from becoming dirty. The cover can be detached and put on the back side of the main body during measurement.
6. OPERATION 6-1 Disconnection and check of power source of the circuit under test DANGER ● To avoid possible electrical shock, do not perform measurements on energized (LIVE) circuits. ● Never make measurements with the battery compartment cover removed. CAUTION ●...
6-2 Insulation Resistance Measurement DANGER ● Always test the circuit or equipment to ensure it is surely de-energized before measurement according to the instruction of 6-1. ● To avoid electrical shock, measurements must be performed on de- energized circuits only. ●...

④ Read the resistance value from the LCD. ⑤ With the test probe still connected to the circuit under test, release the test button to discharge capacitance in the circuit after measurement. DANGER Do not touch the circuit under test immediately after testing. Capacitance stored in the circuit may cause electric shock.
●Terminal connection of insulation resistance test In case of testing insulation of insulated wire and cable against the earth at direct current, connecting - pole of power to cable conductor, + to the earth obtains smaller measuring value, compared with connecting the other way round.
● Principle of Continuity Measurement (Resistance Test) Resistance value can be obtained by applying a certain current to the resistance under test and measuring the voltage generated on the both sides of the resistor under test. Resistance value = Voltage / Current 6-4 Continuous Measurement A lock down feature is incorporated on the test button.
7. FUNCTIONS 7-1 TRAC-LOK MODE (Model 3007A) TRAC mode : Measurement can be conducted while the test button is being pressed. When making continuous measurement, select this mode. LOK mode : When the test button is pressed, measurement can be conducted only once, and output is stopped, then automatically discharged.
8. BATTERY & FUSE REPLACEMENT DANGER ● Never open the battery compartment cover while making measurement. To avoid possible electrical shock, disconnect the test probe before opening the cover for battery and fuse replacement. ● Replacement fuse must be have the following rating. Fast acting type, F 500mA/600V, φ...
9. CASE AND STRAP BELT ASSEMBLY By hanging the instrument around the neck, both hands can be used freely for easy and safety working. Pass the strap belt down through the side panel of the main body from the top, and up through the slots of the probe case from the bottom.
10. CLEANING OF THE INSTRUMENT ● When cleaning the instrument, wipe it with a silicon cloth or soft cloth to remove dust or dirt. ● When it is hard to remove the dirt, wipe it with a cloth wet with water and dry the instrument completely after cleaning.
