Digital Display ­ The digital display has 4000 counts LCD readout with 82 segments analog bar graph, auto polarity, decimal point, " " AC, DC RANGE, H APO and unit annunciators. 2. Rotary Switch ­ Select the Function and Range desired. 3. COM Input Terminal ­ Ground input connector. 4. °C °F VHz Input Terminal ­ Positive input connector for Volts, Ohms Frequency, and Temperature. 5. mA Input Terminal ­ Positive input connector for Amp measurements (up to 400mA). 6. A Input Terminal ­ Positive input connector for Amp measurements (up to 10A). 7. Range Switch, (Manual Range) ­ "Range" switch is pushed to select manual ranging and to change ranges. When "Range" switch is pushed on "Range" annunciator on the LCD appears. Push " Range " switch to select appropriate range to be used. Push "Range" switch and hold 2 seconds to return to Autoranging. 8. REL (PEAK MIN/MAX) Switch ­ For resistance, frequency, capacitance and temperature measurements, this button enables the relative change function. When pressed the value is stored, and all new measurements are displayed as their relative difference from the stored value. In current and voltage measurements, this button performs a peak hold finction. The peak hold mode must be calibrated prior to use. To calibrate the peak hold, press the key until the meter displays "CAL". Short the test leads to calibrate. 9. MIN/MAX Switch ­ Press this switch to toggle between the minimum and maximum values. Pressing the button for 2 seconds to escape MIN/MAX mode. 10.Hold Switch ­ This switch is used to hold the measured value for all functions. The held value is displayed along with the H annunciator. Measurements are made ,but the display is not updated. This function can be used in MIN/MAX mode or PEAK MIN/MAX mode. 11.Light Switch ­ This switch turns the backlight on and off. 12.Blue Switch ­ Push the switch to measure AC Voltage/Current or DC Voltage/Current in the Voltage/Current mode, or to measure Resistance or Continuity or Diode in / / mode, or to measure frequency or RPM in Hz/RPM mode. WARNING! 1. DO NOT UNDER ANY CIRCUMSTANCES EXCEED THESE RATINGS: · Voltage is not to exceed 1000 Volts. · Resistance, Capacitance, Logic and Continuity functions are not to be performed on circuits capable of delivering greater than 600 Volts. · Current measurements are not to be performed on circuits capable of delivering greater than 500 Volts 2. To avoid electrical shock hazards and/or damage to the meter: · Do not exceed the voltage ratings for the meter. Use caution when measuring voltage. · Do not use during electrical storms. AC power sources with inductive loads or electrical storms may result in high voltage. High energy transients can damage meter and present a dangerous shock hazard. · Turn off power to the circuit or device being measured before taking resistance and capacitance measurements. Fully discharge all capacitors before measuring. 3. Ensure meter is in proper working order before using. Visually inspect meter for damage. Performing a continuity check can verify proper operation. If the meter reading goes from overload to zero, this typically means the meter is in proper working order. 4. Visually inspect leads for damage before using. Replace if insulation is damaged or leads appear suspect. 5. Never ground yourself when taking electrical measurements. Do not touch exposed metal pipes, outlets, fixtures etc. Keep your body isolated from ground by using dry clothing, rubber shoes, mats, or any other approved insulating material. Keep your fingers behind the finger guards on the probes. Work with others. 6. Before beginning all unknown measurements, set meter to highest possible range. 7. Before breaking a circuit for testing, turn off the power to the circuit. When disconnecting from a circuit, disconnect the hot lead first, then the common lead. 8. Disconnect the meter from the circuit before turning off any indicator, including motors, transformers, and solenoids. 3 4 Overload Protection Function VAC & VDC AAC & ADC Ohms () Diode Continuity Overload Protection 1000V 1A/500V 16A/500V 600VAC/600VDC 600VAC/600VDC 600VAC/600VDC True RMS AC Volt Circuit Connection: Unit of Measure Multipliers For your reference, the following symbols are often used to make measurement easier: Symbol Verbal Multiplier M mega x 1,000,000 k kilo x 1,000 m milli ÷ 1,000 µ micro ÷ 1,000,000 Auto Power Off (APO) The APO sign on the LCD panel indicates the meter is working in the Auto Power Off mode. If the meter idles for more than 30 minutes, the meter automatically turns the power off. When this happens, the state (non-logic measurement) of the meter is saved, the meter can be turned back on by pushing any key switch or changing the rotary switch. The meter will give an alarm in 15 seconds before the meter automatically turns the power off. To disable the auto power off function, power up the meter while pressing either the range, REL or min/max switch.
