  • Page 2: Introduction

    10. Warranty 1: INTRODUCTION The Triplett Model 9045 is a 6000 count, autoranging, True RMS, handheld Digi- tal Multimeter with a 61 segment bargraph in its backlit Liquid Crystal Display. At its core is an LSI (Large Scale Integration) integrated circuit which uses dual slope A/D conversion for stability and accuracy.
  • Page 3 2.9 Check the condition of the test leads before making a measurement. Do not use the test leads if there is damaged insulation or exposed metal. Failure to observe this precaution may result in damage to the meter or injury to the user. Triplett Model 9045...
  • Page 4 2.19 Replace fuses only with exact or equivalent fuses. Do not “bridge” fuses out of circuit. Failure to observe this precaution may result in damage to the meter or injury to the user. Triplett Model 9045...
  • Page 5 The meter will not read AC voltage if it is set to DC, nor will it read DC if it is set to AC. For example, if the meter is set to measure DC Volts, it will not measure a dangerous AC voltage, even if the probes are inserted into a household AC wall outlet. Triplett Model 9045...

  • Page 17 7.1.3 The SELECT Button The 9045 has several test functions available on one position of the rotary FUNCTION switch. To access the different functions, the SELECT button is momentarily pressed, repeatedly if necessary, until the desired function is obtained.
  • Page 18 Test, or Continuity modes. 7.1.6 MAX / MIN Mode The 9045 contains a convenient memory that remembers the Maximum and Minimum values measured by the meter. The feature can be used for a few minutes or several hours to memorize the Maximum and Minimum values measured by the meter.
  • Page 19 Hz (Frequency) and Duty (Duty Cycle) can be measured in two different ways on the 9045. The method chosen depends on the type of measurement be- ing made by the user. The Hz / Duty button is used in both methods. See the following sections for specific information on performing the measurements.
  • Page 20 7.2.1.4 If the display indicates overrange, i.e. “OL”, disconnect the test probes from the circuit immediately! The voltage exceeds the measurement range of the 9045. 7.2.1.5 To set the range manually, press the RANGE button, repeatedly if neces- sary, to select the desired range. Observe the position of the decimal point and the annunciators to identify the selected range.

The voltage exceeds the measurement range of the 9045. 7.2.2.5 To set the range manually, press the RANGE button, repeatedly if neces- sary, to select the desired range. Observe the position of the decimal point and the annunciators to identify the selected range.
