CHAPTER 2 PRODUCT FEATURES Description The Megohmmeter Model 6505 is a portable instrument housed in a rugged field case and operates on either battery or line power. It performs voltage, insulation, and capacitance measurements. This instrument contributes to the safety of electrical installations and equipment. Features include automatic calculation and presentation of the Dielectric Absorption Ratio (DAR) and Polarization Index (PI). The Model 6505 displays the test voltage, insulation resistance and the leakage current during the test. Capacitance of the sample and discharge voltage present at the test leads is displayed at the conclusion of the test. The Model 6505 is designed with the highest level of built-in safety fea- tures. This meter incorporates test inhibit capabilities which will not allow test voltages to be generated if a live sample is detected. The test termi- nals are recessed to ensure operating safety. Features: • Test voltage combination of 500V, 1000V, 2500V and 5000V •... -

Serial Number To view the serial number of the instrument, keep the DISPLAY button pressed and turn the switch to the MΩ-500V position. Software Version To view the internal software version of the instrument, keep the DISPLAY button pressed and turn the switch to the MΩ-1000V position. Technical documentation on Understanding Insulation Resistance Testing is available on our website at www.aemc.com/techinfo. Voltage Measurement As soon as the switch is set to an insulation measurement position, the instrument automatically measures the presence of any AC/DC voltage. This voltage is measured at all times and indicated on the small display unit. The instrument automatically determines AC or DC. The AC measurement is an RMS value. -

Connect the red high-voltage lead between earth and the + terminal of the instrument. Connect the black high- voltage lead between one phase of the motor and the - terminal of the instrument. Strong Insulation For a very high insulation value, connect the small blue high-voltage lead between the rear earth pick-up jack of the black lead and the G terminal of the instrument. This serves to reduce any external influence and obtain a more stable measurement. Cable Connect the red high-voltage lead between the braid and the + terminal of the instrument. Exterior Core Insulation Insulation Connect the black Braid high-voltage lead between the core and the - terminal of the instrument. Connect the blue high-voltage lead between the insulation and the G terminal of the instrument. The guard serves to eliminate the effect of surface leakage currents.

Page 24: Adjustment Of The Variable Test Voltage
• Set the switch to MΩ 50-5000V to make the measurement. • This value is retained in a non-volatile memory. Adjustment of the Maximum Test Voltage The user can set a maximum generated voltage to prevent any accidental over-voltage tests being conducted in error. • Set the switch to SET V LOCK SET V LOCK SET V LOCK • The maximum test voltage flashes and can be adjusted using the ▲ and ▼ buttons. • Turn the switch to an insulation measurement setting to make measurements. • The maximum test voltage value is retained in a non-volatile memory. It will be displayed for a few seconds on selection of an affected range. (e.g. if the maximum voltage is 750V, it will be applied and displayed on all switch settings from 1000V up).

Page 25: Error Messages
• The insulation resistance is too low. • Check your connections. The + and - terminal of the instrument may be short-circuited. • The insulation resistance is outside the measurement range. • Check your connections. One of the terminals of the instrument may be disconnected or the value measured is > 4TΩ. • The voltage present on the terminals is greater than 25V or 35Vpeak. • The instrument alerts you but does not prevent making the measure- ment. • The voltage present on the terminals is too high for a measurement to be made: peak V > 0.4 Un The test voltage, Un, is indicated by the setting of the switch. • Eliminate the voltage and restart the measurement. • Indicates that the protective fuse of the G terminal is defective. • Replace the fuse as indicated in § 5.2.

Page 26: Maintenance
CHAPTER 5 MAINTENANCE Use only factory specified replacement parts. AEMC will not be held ® responsible for any accident, incident, or malfunction following a repair done other than by its service center or by an approved repair center. Recharging the Battery If the symbol displays, the battery needs to be recharged. Connect the instrument to the 115V power cord via the connector (charging starts automatically). -
Page 27: Fuse Replacement
• Using a coin or a flathead screwdriver, unscrew the fuse holder and remove the fuse. • Only replace with the type of fuse specified on the label inside the unit’s cover: 0.1A - Fast Acting - 380V, 5x20mm, 10kA NOTE: If after changing the fuse the display still indicates FUSE -G-, the instrument must be returned to the factory for servicing. Cleaning Disconnect the instrument from any source of electricity. Use a soft cloth lightly dampened with soapy water. Rinse with a damp cloth and then dry with a dry cloth. Do not use alcohol, solvents or hydrocarbons. Storage If the instrument is not used for an extended period of time, it is recom- mended to charge the instrument every two or three months.
