It covers all insulation tests up to Resistance MeasurementThe instrument is capable of measuring insulation resistance from 10 K.

2 999 M .Hands-free continuity testingContinuity testing (0-10 with acoustic signal) can be done without pressing the test button. In addition to the display function, an acoustic signal can be activated which sounds if the adjustable limit value is Instrument measures voltages > 25V .. 600 V discharge for capacitive circuits after testmeasurementCapacitive devices under test, such as cables and windings, that get charged during the test, are discharged by the circuit detectionDisplays presence of voltages >25V irrespective of function measurement time for Insulation Resistance MeasurementIn normal course, the insulation test terminates and the measured insulation resistance value remains on display for 2 sec after the test key is released.

3 With the Pre-selectable measurement time feature, the insulation test continues and the measured value remains on the display for the pre-determined time. Pre-selectable time: 10 sec - 5 limit checks (Go/ No-go option) for M An acoustic signal can be generated when the measured value ofinsulation resistance falls below an adjustable limit resistance null facilityThe instrument provides a facility to compensate the resistance of the leads for an accurate measurement of low of MIN/MAX valuesIn addition to the display of the actual measured value, the minimum or maximum value can constantly be updated or Memory for last 50 readings The instrument provides a facility to store and recall 10 values in each of the 5 ranges of insulation resistance fuse indicationThe display FUSE points to a blown battery indicationAutomatic display of the Symbol when battery cells are Watch This function allows you to measure elapsed time up to 1 off function The instrument turns off automatically.

4 If any of the keys or the selector switch have not been activated for about 10 minutes in insulation range and 5 minutes in other ranges or can be switched to continuous holster for rough dutyA holster of soft rubber with tilt stand protects the meter against damage in the case of shock and Resistances Measurement ( .. ) Low resistances can be measured up to . There are two measuring ranges for Low .: and 1) For Insulation Resistance Range: Terminal voltage on open circuit (DC)-0% + 30% of rated voltage Short circuit current < 2 mA Test current on load 1 mA at minimum pass values of Insulation as specified in VDE 0413 Part ) For Low Ohms/Continuity Ranges: Lead Resistance Compensation: 0 - Open circuit voltage 5V + 1V SupplyBattery6 x V cells IEC LR6 (Nickel cadmium rechargeable cells may be used)Service LifeTypically 2500 x 5 sec.
