５．Preparation for Measurement ５−１ Checking Battery Voltage ①Set the function selector switch to any position other than "OFF". ②When the display is clear without "BATT" showing, proceed to measurement. ③When the display blanks or "BATT" is indicated, replace the batteries according to section 8: battery replacement. NOTE ● It is possible that display is kept in blank while the function selector switch is set to a position other than "OFF".
６．Measurement ６−１ Current Measurement WARNING ●Do not make measurement on a circuit above 750V AC. This may cause shock hazard or damage to the instrument or equipment under test. ●Transformer jaw tips are designed not to short the circuit under test. If equipment under test has exposed conductive parts, however, extra precaution should be taken to minimize the possibility of shorting. ●Do not make measurement with the battery compartment cover removed from the instrument.
③Take the reading on the display. NOTE ● During current measurement, keep the transformer jaws fully closed. Otherwise, accurate measurement cannot be made. The maximum measurable conductor size is 54.5mm in diameter. ● When measuring a larger current, the transformer jaws may buzz. This is not a fault and does not affect the accuracy at all. ６−１−２ Peak Current Measurement ①Set the function selector switch to the "∼400A" or "∼2000A" position. ②Press the mode switch to select the peak mode.
６−２ Voltage Measurement WARNING ●Do not make measurement on a circuit above 750V AC or 1000V DC. This may cause shock hazard or damage to the instrument or equipment under test. ●Do not make measurement with the battery compartment cover removed. Black test lead Red test lead ６−２−１ DC Voltage Measurement ①Set the function selector switch to the " V" position. ②Slide the terminal cover to the left. Plug the red test lead into the V/Ω terminal and the black test lead into the COM terminal.
６−３ Resistance Measurement WARNING ●Before attempting to make measurement, make sure that the circuit under test is not live. The instrument is protected against a voltage up to 600V. ●Do not make measurement with the battery compartment cover removed. Black test lead Red test lead ６−３−１ Resistance Measurement (Normal Mode) ①Set the function selector switch to the "Ω/ " position. ②Slide the terminal cover to the left.
６−３−２ Continuity Check ①Set the function selector switch to the "Ω/ " position. ②Slide the terminal cover to the left. Plug the red test lead into the V/Ω terminal and the black test lead into the COM terminal. ③Press the mode switch to set the instrument to the continuity check mode. The measuring range is fixed to 400Ω and the " " symbol is shown on the display. ④Short the tip of the test leads and make sure that the display reads "0" and the buzzer beeps.
７．Notes on Functions ７−１ Data Hold This is a function used to freeze the measured value on the display. ①Press the data hold switch. The reading becomes frozen and the "H" symbol is shown on the display, indicating the instrument in the data hold mode. ②To exit the data hold mode, press the data hold switch again to release it. NOTE ● When the function selector switch is turned while the instrument is in the data hold mode, the data hold function remains activated.
②To enable the sleep function, turn the function selector switch back to "OFF", then to any other position. NOTE ● The instrument consumes small amount of current in the sleep mode. When the instrument is not in use, make sure to set the function selector switch to "OFF". ７−３ Recorder Output Only on the "∼400A" or "∼2000A" range, DC voltage proportional to the input current is output from the OUTPUT terminal. ①Set the function selector switch to the "∼400A" or "∼2000A" position.
［How to attach a pair of leads to the recorder output plug］ Attach one end of the leads to the recorder output plug observing correct polarity, then connect the other end to the recorder. DANGER Never apply voltage to the output terminal. ７−４ Mode Switching Function On a AC current ("∼400A" or "∼2000A") or the resistance(Ω/ ) range, press the mode switch to cycle through the measurement modes.
８．Battery Replacement WARNING ●To avoid electric shock hazard, make sure to set the function selector switch to "OFF" and remove the test leads from the instrument before trying to replace batteries. CAUTION ●Do not mix new and old batteries. ●Make sure to install batteries in correct polarity as indicated in the battery compartment. NOTE ● If the instrument is powered on, but the display blanks or "BATT" is shown on the display, replace the batteries.
９．Optional Accessories ● Multi-Tran MODEL 8008 extends the capability of MODEL 2002PA or MODEL 2002R, allowing measurement up to 3000A or on a large bus-bar or conductor. ①Set the function selector switch to "∼400A". ②As shown in the figure below, clamp MODEL 2002PA or MODEL 2002R onto the pickup coil of MODEL 8008. ③Clamp MODEL 8008 onto the bus-bar or conductor under test. ④Take the reading on MODEL 2002PA or MODEL 2002R and multiply it by 10.
