Application around and removal from hazardous live conductors is permitted SAFETY INFORMATION The ACDC-100 Series Digital Clampmeters conform to EN61010-1:2001; EN61010- 2-• 032:2002; CAT III 600 V, class 2 and pollution deg.2 This instrument is EN61010-1 certified for Installation Category III (600V). It is • recommended for use in distribution level and fixed installations, as well as lesser installations, and not for primary supply lines, overhead lines and cable systems. Do not exceed the maximum overload limits per function (see specifications) nor the limits • marked on the instrument itself. Never apply more than 600 Vdc/600 V ac rms between the test lead and earth ground. Warnings and Precautions Before and after hazardous voltage measurements, test the voltage function on a known • source such as line voltage to determine proper meter functioning. Disconnect the test leads from the test points before changing meter functions.• Inspect the Clampmeter, test leads and accessories before every use. Do not use any • damaged part. Never ground yourself when taking measurements. Do not touch exposed circuit elements • or test probe tips. Do not operate the instrument in an explosive atmosphere.• To reduce the risk of fire or electric shock, do not expose this product to rain or moisture.• The meter is intended only for indoor use. To avoid electrical shock hazard, observe the • proper safety precautions when working with voltages above 60 VDC or 30 VAC rms. These voltage levels pose a potential shock hazard to the user.6 Before and after hazardous voltage measurements, test the voltage function on a known • source such as line voltage to determine proper meter functioning. Keep your hands/fingers behind the hand/finger barriers (of the meter and the test leads) • that indicate the limits of safe access of the hand-held part during measurement. Inspect test leads, connectors, and probes for damaged insulation or exposed metal before • using the instrument. If any defects are found, replace them immediately. This Clamp-on meter is designed to apply around or remove from uninsulated hazardous • live conductors. Individual protective equipment must be used if hazardous live parts of the installation could be accessible. Exercise extreme caution when: measuring voltage >20 V // current >10 mA // AC power • line with inductive loads // AC power line during electrical storms // current, when the fuse blows in a circuit with open circuit voltage >1000 V // servicing CRT equipment. Remove test leads before opening the case to change the battery.• Disconnect circuit power and discharge all high-voltage capacitors before testing • resistance,continuity, diodes, or capacitance. To avoid false readings, which could lead to possible electric shock or personal injury, • replace the batteries as soon as the low battery indicator () appears.

UNPACKING AND CONTENTS

INTRODUCTION The ACDC-100 and ACDC-100 TRMS Clamp-On meters are 1000 Amp / 600 V clamp meters with 50 mm jaw opening for industrial applications. The features include large conductor size and in-rush current measurement along with AC / DC voltage, AC / DC current, Resistance, Continuity and Diode Tests. FEATURES Alignment marks (see Fig. 1) Place conductor within the jaws at the intersection of the indicated marks as close as possible to maximize the accuracy of the reading. MAX / HOLD The HOLD feature freezes the display when the button is pressed. The MAX feature compares and displays the measured maximum value as fast as 30ms with auto-ranging capability.7 HOLD Press the HOLD button momentarily toggles to hold mode for all of the functions. To release the HOLD feature momentarily press the HOLD button. MAX Press the HOLD button for 1 second or more activates the MAX HOLD feature for the VDC, VAC and ACA functions. To release the MAX HOLD feature press the HOLD button for 1 second or more. r Relative Zero mode Relative Zero mode allows the user to offset the subsequent meter measurements with the displayed reading as the reference value. The display will now show readings relative to the stored reference value. That is, display = reading - stored value. Pressing the button momentarily toggles to relative mode. SELECT / Backlight ( ) Press Backlight button more than 1 second, enable/disable Backlight. Press the SELECT / Backlight button to step through the manually selected Aand Ω functions. A→ Aand Ω → → → Manual or Auto-ranging Press the RANGE button momentarily to select manual-ranging mode. The LCD symbol turns off. Press the button momentarily again to step through the Ranges. Press and hold the RANGE button for more than 1 second to resume auto-ranging. Auto Power Off function The clamp meter powers down automatically after approximately 30 minutes of inactivity. To turn it back on, move the function selector switch to OFF and back to a measuring function. To disable Auto Power Off, press and hold the HOLD button while moving the slide switch to the desired function from OFF. OPERATION DC Voltage (see Fig. 1) Set the Function Switch to 1. V. Connect the test leads: Red to 2. +, Black to COM. Connect the test probes to the circuit test points. 3. Read the display, and if necessary, correct any overload (4. 0L) conditions. AC Voltage (see Fig. 1) Set the Function Switch to 1. V. Connect the test leads: Red to 2. +, Black to COM. Connect the test probes to the circuit test points. 3. Read the display, and if necessary, correct any overload (4. 0L) conditions.8 AC Current (see Fig. 2) Set the Function Switch to A1. position. Select AC current using the SELECT button. 2. Open spring-loaded clamp by pressing the lever on left side of meter. 3. Position clamp around one wire or conductor and release the clamp lever. Make sure that 4. the clamp is entirely closed. The clamp must be positioned around only one conductor. If it is placed around two or more current carrying conductors, the reading is FALSE. Read the displayed value, and if necessary, correct any overload (5. 0L) conditions. DC Current (see Fig. 2) Set the Function Switch to A1. position. Select DC current using the SELECT button. 2. Open spring-loaded clamp by pressing the lever on left side of meter. 3. Position clamp around one wire or conductor and release the clamp lever. Make sure that 4. the clamp is entirely closed. The clamp must be positioned around only one conductor. If it is placed around two or more current carrying conductors, the reading is FALSE. Read the displayed value, and if necessary, correct any overload (5. 0L) conditions. CAUTION Using the Resistance, Continuity, Diode or Capacitance functions on a live circuit will produce false results and may damage the instrument. In many cases the suspected component must be disconnected from the circuit to obtain an accurate measurement reading. Resistance (see Fig. 3) Set the Function Switch to 1. Ω. Connect the test leads: Red to 2. +, Black to COM. Turn off power to the circuit being measured. 3. Discharge any capacitors that may influence the reading. 4. Connect the test probes across the resistance. 5. Read the display. If 6. 0L appears on the highest range, the resistance is too large to be measured or the circuit is an open circuit. Continuity (see Fig. 3) Set the Function Switch to 1. Ω and press the SELECT button until is displayed. Connect the test leads: Red to 2. +, Black to COM. Turn off power to the circuit being measured. 3. Discharge any capacitors that may influence the reading. 4. Connect the test probes across the resistance or the two points of test. 5.
