2: SAFETY RULES & WARNINGS 2.1 Read all instructions in this manual before using this meter. Failure to do so may result in damage to the meter or injury to the user. 2.2 Prior to using the meter in any situation which could result in injury to the user, in order to verify that the meter is functional and producing a valid reading, test the meter on a circuit(s) known to have potentials equivalent to the potential that is to be measured.
2.10 Make sure test leads are properly inserted and seated in the meter’s input jacks. A loose test lead may cause the user to believe that no hazard exists, when in fact, dangerous voltages or currents may be present. Failure to observe this precaution may result in damage to the meter or injury to the user. 2.11 Do not touch the tips of the test leads when making a measurement. Do not touch live circuitry when making a measurement.
2.20 Do not apply voltages to the input of the meter which are elevated above the earth ground potential by more than 600V AC/DC. Doing so may damage the meter and/or injure the user. 2.21 Do not continue to use meter when the “low battery” symbol is displayed. The displayed reading may be in error and lead the user to believe that no hazard exists, when in fact, dangerous voltages or currents may be present. Failure to observe this precaution may result in damage to the meter or injury to the user. 2.
2.30 Do not touch the metallic portion of one test lead if the other test lead is connected to a live circuit. The current from the live circuit may pass through the meter and appear on the unconnected test lead. Failure to observe this warning may result in user injury. 2.31 Do not attempt to use meter when no display is present on LCD. Doing so may damage the meter and/or injure the user. 2.32 Use caution when measuring circuits containing capacitors.
2.39 Do not use the meter if it may have been damaged in transport. Failure to observe this precaution may result in damage to the meter or injury to the user. 2.40 Always connect one of the meter’s alligator clips to the low side of a power circuit first. Never clamp onto a hot wire first, (usually red, black, or blue in AC wiring circuits.) If you clamp onto a hot wire first, and touch the other probe, you could receive a shock.
2.47 Observe whether HOLD function is activated. The meter may not show the presence of dangerous potentials when HOLD is activated. For example, if HOLD is applied when the meter is reading zero, and 120VAC is subsequently applied, the meter will continue to read zero. Failure to observe this precaution may result in damage to the meter or injury to the user. 2.48 Do not attempt to test charged capacitors. Only discharged capacitors may be tested.

The bargraph visually indicates how the input quantity compares with the measurement range of the meter. For example, if the meter is set to the 6 Volt DC range, and 3 volts is applied to the meter’s input, the bargraph would extend from 0 to 30, half the length of the bargraph, indicating that the measured quantity is 1/ 2 of the range setting. This feature is often used for “nulling” or “peaking” adjustments, which are easier to visualize on the bargraph, rather than examining the numeric digital reading.
7.1.2 Auto Power Off The 9045 has Defeatable Auto Power Off. This power saving feature automatically turns the meter off 15 to 20 minutes after the last button press or switch actuation. The annunciator appears on the LCD when the feature is activated. To defeat the Auto Power Off, and keep the meter running continuously, hold down the SELECT pushbutton while turning the meter on. The annunciator will not appear in the display. 7.1.
7.1.5 REL Mode Press the (REL) button to make subsequent readings RELative to the present reading, or to “zero out” any zero error. The button is usually used to zero out a residual resistance reading on the 600Ω range, or the residual stray capacitance reading on the 40nF range. This button does not work in all ranges or modes. For example, it doesn’t work in the Frequency, Diode Test, or Continuity modes. 7.1.
To select the range manually, press the RANGE button. The first press of the button will turn off the Auto annunciator, and the meter will be in the range the meter was on when the Auto annunciator was on. Subsequent presses of the button will manually select additional ranges. The actual range selected can be determined by observing the decimal points and range annunciators on the LCD display.
7.2.1.3 Connect the test probes to circuit being measured. The LCD will display the DC voltage. Note the position of the decimal point and the units annunciator when reading the voltage. 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 necessary, to select the desired range.
7.2.3 DC Current Measurement WARNING!!! If the magnitude of the current to be measured is unknown, always start by setting the meter to the highest range, and then to lower ranges, until a satisfactory reading is obtained. Do not rotate the FUNCTION switch with the input applied to the meter. If the input current is higher than 10A, do not attempt to measure! Use caution when measuring current in a circuit with voltages above 50 VDC.
7.2.4 AC Current Measurement: WARNING!!! If the magnitude of the current to be measured is unknown, always start by setting the meter to the highest range, and then to lower ranges, until a satisfactory reading is obtained. Do not rotate the FUNCTION switch with the input applied to the meter. If the input current is higher than 10A, do not attempt to measure! Use caution when measuring current in a circuit with voltages above 30 VAC.
7.2.4.6 To set the range manually, press the RANGE button, repeatedly if necessary, to select the desired range. Observe the position of the decimal point and the annunciators to identify the selected range. 7.2.5 Resistance Measurement WARNING!!! Do not apply voltage or current to the meter when the FUNCTION switch is set to 7.2.5.1 Connect the black test lead to the COM jack, and the red test lead to the jack. 7.2.5.2 Set the FUNCTION switch to the position. The LCD display will indicate overrange (i.
7.2.6.1 Connect the black test lead to the COM jack, and the red test lead to the jack. 7.2.6.2 Set the FUNCTION switch to the position. Press the SELECT button, repeatedly if necessary, to select the Continuity Beeper mode. The annunciator will turn on when the Continuity Beeper mode is selected. The LCD display will indicate overrange (i.e. “OL”). 7.2.6.3 Connect the test leads to the device or circuit being tested.
7.2.8 Measuring Capacitance WARNING!!! Do not connect a charged capacitor to the meter. Doing so may damage the meter or injure the user. Do not apply voltage or current to the meter when the FUNCTION switch is set to 7.2.8.1 Connect the black test lead to the COM jack, and the red test lead to the jack. 7.2.8.2 Set the FUNCTION switch to the position. Press the SELECT button, repeatedly if necessary, to select the Capacitance Test mode.
7.2.9 Measuring Temperature WARNING!!! Do not attempt to measure the temperature of any surface that is electrically “live”. Failure to observe this precaution may result in injury to the user. Do not apply voltage or current to the meter when the FUNCTION switch is set to 7.2.9.1 Remove the test leads from the input jacks of the meter. 7.2.9.2 Set the FUNCTION switch to the position. Using the SELECT button, select the desired units of measurement (C or F).
7.2.10.3 Connect the test leads to the circuit to be measured, and read the frequency on the LCD display. Observe the position of the decimal point and the annunciator to determine the units of measure (i.e. Hz, kHz, MHz, etc) 7.2.10.4 To measure Duty Cycle, press and release the Hz/DUTY button. The display will change to a Duty Cycle readout in %. Press the button again to return to the Frequency measurement mode. 7.2.10.
