Introduction Thank you for purchasing your REED R5040 1000A AC/DC True RMS Clamp Meter. Please read the following instructions carefully before using your instrument. By following the steps outlined in this manual your meter will provide years of reliable service.
• Remove the battery if the meter is to be stored for long periods. • Always discharge capacitors and remove power from the device under test before performing diode, resistance, or continuity tests. • Voltage checks on electrical outlets can be difficult and misleading because of the uncertainty of connection to the recessed electrical contacts. • If the equipment is used in a manner not specified by the manufacturer, the protection provided by the equipment may be impaired. Features • Measures AC/DC current/voltage, resistance, capacitance, frequency, duty cycle, and temperature • 50,000-count backlit LCD display and analog bargraph • Low battery and overrange indicators • Built-in non-contact voltage detector with LED indicator...
Set the rotary function switch to the 1000ADC, 600ADC, 1000AAC, or 600AAC range. If the range needed is not known, select the higher range first then move to the lower range if necessary. R5040 R5040 Press the trigger to the open jaw and fully enclose one conductor. The LCD will display the reading. AC/DC Voltage Measurements Insert the black test lead into the negative COM terminal and the red test lead into the positive V terminal.
Diode and Continuity Measurements Insert the black test lead into the negative COM terminal and the red test lead into the positive V diode terminal. Turn the rotary function switch to the Ω position. Press the MODE button until the Diode Test indicator appears on the display. Touch the test probes to the diode under test.
Temperature Measurements To avoid electric shock, disconnect both test probes from any source of voltage before making a temperature measurement. Set the function switch to TEMP. Press the MODE button to change between °C and °F. Insert the Temperature Probe into the negative COM and the positive V terminals, making sure to observe the correct polarity.
Data Hold While taking a measurement, press the HOLD button to freeze the current reading on the display. While in this mode, a HOLD symbol will appear. Press the HOLD button again to exit and resume normal operation. Auto and Manual Range When the meter is first turned on, it automatically goes into AutoRanging. This automatically selects the best range for the measurements being made and is generally the best mode for most measurements.
REED Instruments guarantees this instrument to be free of defects in material or workmanship for a period of one (1) year from date of shipment. During the warranty period, REED Instruments will repair or replace, at no charge, products or parts of a product that proves to be defective because of improper material or workmanship, under normal use and maintenance.
