Major tech MT1885, Instruction Manual

Page: 18 / 20

Function Range
Enclosure Double molded, waterproof
Shock (Drop Test) 6.5 feet (2 meters)
Diode Test
Test current of 0.9mA maximum, open circuit
voltage 3.2V DC typical
Continuity Check Audible signal will sound if the resistance is less
than 50Ω (approx.), test current <0.9mA
Temperature Sensor Requires type K thermocouple
Input Impedance >10MΩ VDC & >10MΩVAC
AC Response True RMS
AC True RMS: The term stands for “Root-Mean-Square," which
represents the method of calculation of the
voltage or current value. Average responding
multimeters are calibrated to read correctly only
on sine waves and they will read inaccurately on
non-sine wave or distorted signals. True RMS
meters read accurately on either type of signal.
ACV Bandwidth 50Hz to 1KHz
Crest Factor ≤3 at full scale up to 500V, decreasing linearly to
≤ 1.5 at 1000V
Display 60,00 count backlit liquid crystal with bargraph
Overrange indication "OL" is displayed
8 2 AUDIBLE CONTINUITY .1 .
Audible threshold: Less than 50Ω Test current MAX. 0.3mA
Overload protection: 250VDC/AC RMS.
Note: Accuracy specifications consist of two elements:
• (% reading)-This is the accuracy of the measurement circuit.
• (+ digits)-This is the accuracy of the analog to digital converter.
Note: Accuracy is stated at 18 to 28°C (65 to 83°F) and less than
75%RH.
