DANGER

• Never make measurement on a circuit in which the earth potential exceeds 600V to avoid electrical shocks.
• Do not make measurement when thunder is rumbling.
• If the instrument is in use, stop the measurement immediately and remove the instrument from the measured object.
• Put insulated protective gears when there is a danger of electrical shock hazard.
• Do not attempt to make measurement in the presence of flammable gasses, fumes, vapor or dust. Otherwise, the use of the instrument may cause sparking, which can lead to an explosion.
• Never attempt to use the instrument if its surface or your hand is wet.

• First, connect the lester to Ihree-phase system and then press the push switch button.
• lf the cables are accidentally disconnected, release your hand from the push switch button and stop measurement.
• Don’t touch the disconnected cables while the push switch button is being pressed dowvn.
• Stop using the test lead if the outer jacket is damaged and the inner metal or color jacket is exposed.
• Do not install substitute parts or make any modification to the instrument. Return the instrument to Kyoritsu or your distributor for repair or re-calibration.

CAUTION

• Even if all missing phase indicators are off, one phase might be live: care should be taken to avoid getting electric shock.
• Max continuous measurement time differs depending on voltages. Please refer to continuous measurement time written in this document and measure each voltage within each limited time.
• Do not expose the instrument to the direct sun, extreme temperatures or dew fall.
• Use a damp cloth and detergent for cleaning the instrument. Do not use abrasives or solvents.
• This instrument isn’t dust & water proofed. Keep away from dust and wateer.

Specifications

Operating instructions

WARNING
First, connect the Tester to Three-phase system and then press the push switch button. lf the cables are accidentally disconnected, release your hand from the push switch button and stop measurement. Don’t touch the disconnected cables while the push switch| button is being pressed down.
CAUTION
Even if all missing phase indicators are off, one phase might be live: care should be taken to avoid getting electric shock. Max continuous measurement time differs depending on voltages. Please refer to continuous measurement time written in this document and measure each voltage within each limited time.

1. Connect colour coded alligator clips or prods to the terminals of a 3-phase power source where a rotating electrical machine such as a motor will be connected or input to a building.
2. Press the push switch button located on top of the unit. Keep this button pressed during phase sequence or open phase check. When the push switch button is released it immediately goes off.
3. Make sure that all of the three lamps for phase check are on. If So, there IS no open phase. When any of the three lamps is Not on there is open phase.  Open phase check Open phase on terminal Lamp L1″ Is not on where Red alligator clip Is connected. Open phase check Open phase on terminal Lamp “L2” is not on where Whight alligator clip is connected. Open phase check Lamp “L3” is not on Open phase on terminal where Blue alligator clip IS Connected. When the open phase checCk lamps are not on the rotating disc does not turn.
4. Check the rotating direction of the inside disc through the phase sequence indication window. When the rotating disc turns counter-clockwise alternate the connection of the two of the three alligator clips. Then, the rotating disc will turn clockwise. * When the rotating disc turns clockwise phase sequence isL1,L2 and L3 in order of the power Source terminals where the Red, Whight and Blue alligator clips are connected.
