#61-494 #61-495 1 490 Series 3 Industrial Grade Multimeter 2 M/M/A 4 True RMS Data Logging 5 M/M/A 1. LCD Display 2. Function Buttons 3. Data Log Features 4. Rotary Function Switch 5. Input Connectors True RMS Data Logging 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.
. 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.
Range Button • Pressing the range button for 2 seconds toggles the meter between auto and manual ranging mode. • When in manual range mode, pressing the button changes the measurement range. • Pressing the range button while in AC voltage measurements for > 2 seconds enables the dB/dBm function. • While in dB/dBm mode, pressing the range button toggles between dB and dBm. dB/dBm Function • The reading of dB or dBm appears on the secondary display.
Auto power off: The meter turns itself off within 30 minutes if no controls or settings are changed. Restore power by switching dial. Power-up Options: Press button while turning meter on from OFF position.
Voltage Burden: Input Protection: 800mV max. for mA input; 1V max. for A input. Equipped with high energy fuse. 1A, 600V, IR 10kV fuse for mA input 15A, 600V, IR 100kV fuse for A input. AC Conversion Type: AC Coupled, True RMS responding AC+DC Volts: Same as ACVRMS +1.00% + 8 digits Crest Factor: +1.5% addition error for C.F. from 1.4 ~ 3 +3.0% addition error for C.F. from 3 ~ 4 To Measure Voltage: 1. Plug the Black test lead into the COM port and the Red test lead into the VΩHz port. 2.

Continuity Check General Specifications V connector: Temperature coefficient: Battery Life: Physical Characteristics Dimensions: To Verify Continuity: A continuity test ensures that all circuit connections are intact. 1. Plug the Black test lead into the COM port and the Red test lead into the VΩHz port. 2. Set the rotary switch to the position. 3. Press the blue button until is shown in the display. 4. Connect the test leads to the circuit to be measured.
Warning To avoid electrical shock, remove test lead before opening the cover. Repairs or servicing not covered in this manual should only be performed by qualified personnel. Maintenance Battery Installation or Replacement: 1. The #61-492 is powered by one 9 volt battery. 2. Remove the test leads from the front terminals and turn the meter off. 3. Remove the screw from the battery cover and lift to remove. 4. Replace batteries. 5.
