High Frequency, Solid Aluminum TopType 350’s solid aluminum top assures extremely low impedance. With a typical 4 to 6 nH ESL, the self reso-nant frequency is well above 100 kHz. The very low ESR assures the low impedance rating. The capacitors are fitted with three rugged welded mounting leads to provide maximum resistanceHighlightsOperates to beyond 200 kHz Less than 10 nH ESL Solid aluminum top•••SpecificationsCapacitance

They should be aligned at an interval of 5-10m from the earthed equipment under test. Connect the green wire to the earthed equipment under test, the yellow wire to the auxiliary earth spike P and the red wire to the auxiliary earth spike C from terminals E, P and C of the instrument in order.Note : Make sure to stick the auxiliary earth spikes in the moist part of the soil. Give enough water where the spikes have to be stuck into the dry, stony or sandy part of the earth so that it may become moist.In case of concrete, lay the auxiliary earth spike down and water it, or put a wet dustcloth etc. on the spike when making measurement.w Earth Voltage MeasurementSet the range switch to EARTH VOLTAGE position in the condition of q. Earth voltage will be indicated on the display. Make sure that the voltage is 10V or less.When the display reads more than 10V, it may result in excessive errors in earth resistance measurement. To avoid this, make measurement after reducing the voltage by turning off the power supply of the equipment under test etc.e Precise MeasurementSet the range switch to 2000Ωposition and press the test button. LED remains illuminated during testing. Turn the range switch to 200Ωand20Ωwhen the earth resistance is low. This indicated value is the earth resistance of the earthed equipment under test.Note : If the auxiliary earth resistance of auxiliary earth spike C is too high to make measurement, the display reads '...'. Recheck the connection of test leads and the earth resistance of auxiliary earth spike.6-3 Simplified Measurement (with Test Probe M-7127)Use this method when the auxiliary earth spike cannot be stuck. In this method, an existing earth electrode with a low earth resistance, such asa metal water pipe, a common earth of a commercial power supply andan earth terminal of a building, can be used with two-terminal method (E,P).Use the simplified measurement probe attached which has a convenient structure that both the safety alligator clip and the test bar are available.q WiringMake connection as shown in the figure.Note :When the simplified measurement probes are not used, short P and C terminals.w Earth Voltage MeasurementSet the range switch to EARTH VOLTAGE position in the condition of q. Earth voltage will be indicated on the display. Make sure that the voltage is 10V or less.When the display reads more than 10V, it may result in excessive errors in earth resistance measurement. To avoid this, make measurement after reducing the voltage by turning off the power supply of the equipment under test etc.e Simplified MeasurementSet the range switch to 2000Ωposition and press the test button. LEDremains illuminated during testing. Turn the range switch to 200Ωand 20Ωwhen the earth resistance is low. This indicated value is the earth resistance of the earthed equipment under test.Note :If the auxiliary earth resistance of auxiliary earth spike C is too high to make measurement, the display reads'...'. Recheck the connection of each test lead and the earth resistance of auxiliary earth spike.r Simplified Measurement ValueTwo-terminal method is used for simplified measurement. In this method, earth resistance value re of earth electrode connected to terminal P is added to true earth resistance value Rx and shown as an indicated value Re.Re = Rx + reIf the re is known beforehand, true earth resistance value Rx is calculated as follows.Rx = Re --- re7. Battery Replacementq Turn off the instrument and disconnect the test probes from the terminals.w Loosen two screws on the bottom of the instrument and remove the battery cover.e Always replace all six batteries in correct polarity.Battery : R6P (AA dry battery) x6r Put the cover back in place and tighten the two screws.8. Notes on Housing Case & Accessories8-1 Case Lid8-2 How to Fit Strap BeltThe instrument is equipped with a strap belt to suspend from the neck to allow both hands to be used freely for easy and safe operation9. Before Sending for ServiceIf this instrument should fail to operate correctly, return it to your nearest distributor stating the exact nature of the fault. Before returning the instrument follow the trouble-shooting guide shown below.If the instrument does not turn on;Check whether batteries are missing or they are installed incorrect polarity. Note that batteries were not installed in the instrument at the time of shipment.If the display reads '1...' in earth voltage measurement;A voltage exceeding 200V is being applied to the instrument.Halt the measurement immediately, otherwise the instrument may be damaged.If the display reads '...' in normal earth resistance measurement;Stick the auxiliary earth spikes deeper into the earth, or stick them at other locations; orAdd moisture to the part of the earth where C auxiliary earth spike is stuck ( connected with the red wire ); andShort the three test leads and check if the display indicates a value near ' 0.00 '. (See section 6 for details.)If the display reads '...' in simplified earth resistance measurement;Check if the connection to a metal water pipe, a common earth of commercial power supply, etc., is secure; orUse another metal water pipe, common earth of commercial power supply, etc.10. ServiceIf this instrument should fail to operate correctly, return to your nearestdistributors stating the exact nature of the fault.。
