User manual IDEAL 320 SERIES CONTRACTOR GRADE MULTIMETER

#61-322 #61-324 320 Series Contractor Grade Multimeter 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. 2 2 1 5 3 4 1. MIN/MAX Switch · Pressing this button once results in the displayed maximum value of the current reading. · Pressing the min/max button once more results in the displayed minimum value of the current reating. · If pressed a third time "Max Min" will flash on the LCD indicating that the minimum and maximum value are being recorded while the current reading is displayed. · Pressing the min/max button for >2 seconds exits the Min/Max mode. 3 2. RS-232 Button (61-324 only) · Pressing the RS-232 button activates data acquisition · When the RS-232 button is pressed RS232 will appear in the upper middle of the LCD display · Data will be sent to the computer through the optical RS-232 connection. · Press the RS-232 button again to stop data acquisition 3. Range Button · Pressing the range button selects the manual ranging mode. · When the range button is pressed RANGE will appear in the upper left of the LCD display. · When in the manual range mode, pressing the range button changes the meaurement range. · To return to auto ranging, hold the range button for >2 seconds. 4. Hold Switch · The hold button is used to hold the mesured value for all functions. · The value is displayed along with the H annunciator. · This function can be used in the min/max or peak min/max mode. 5. Backlight Buttong (61-324 only) · Pressing the backlight button enables a light source allowing the end-user to view the LCD in dark areas. Auto Power Off (APO) If the meter idles for more than 10 minutes, the meter automatically turns the power off. When this happens, the state (nonlogic 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, RS-232 or min/max. button. 4 Overload Protection Function VAC & VDC AAC & ADC Ohms () Diode Continuity Overload Protection 1000V A input: 1A(600V) fast blow fuse µA input: 600V RMS 600VAC/600VDC 600VAC/600VDC 600VAC/600VDC 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 5 True RMS AC Volt Circuit Connection: Range 600mV 6V 60V 600V 1000V Resolution 100µV 1mV 10mV 100mV 1V Max.

The meter displays total resistance through all possible paths between the probe-tips. These multiple paths may result in measurements that do not correspond to the ohm value indicated by the resistor color code. 12 Determining Resistor Values: To determine the value of a resistor, use the color bands on the resistor and the table on the following page. Resistor Color Code Table 1st Color Digit Black 0 Brown 1 Red 2 Orange 3 Yellow 4 Green 5 Blue 6 Violet 7 Gray 8 White 9 Gold Silver No Color Example: 2nd Tolerance Digit Multiplier (Percentage) 0 1 1 10 2 100 3 1,000 4 10,000 5 100,000 6 1,000,000 7 10,000,000 8 100,000,000 9 1,000,000,000 +/- 5% +/- 10% +/- 20% 1st color band is blue so the first digit is a 6 2nd color band is red so the second digit is a 2 3rd color band is yellow so multiply 62 x 10,000 4th color band is gold so the tolerance is ±5% Your Resistor value is 620,000 Ohms (620k) with a tolerance of ±5%. 13 Blue Red Yellow Gold Diode Testing Function Resolution Accuracy Max.Test Max.Open Current Circuit Voltage 1mV * For 0.4V to 0.8V.
