Monarch 110 Operating Instructions, Continuity Measurements, Low Battery Condition

MODEL 110 AUTORANGING DIGITAL MULTIMETER

5.5 Continuity Measurements

WARNING

Before making any in-circuit measurements, remove power from the circuit being tested and discharge all capacitors in the circuit.

1.Connect the red test lead to the ‘:’ jack and the black test lead to the ‘COM’ jack.

2.Set the Function Selector switch to the : range and press

the blue button to select the function.

3.Remove power from the circuit being tested and discharge all capacitors in the circuit.

4.Connect the test leads to the portion of the circuit to be measured.

5.When the impedance of the circuit between the test leads is less than 40 ohms, the instrument will sound a continuous 2kHz tone.

Note: A Continuity test may be used to determine either Open or Short circuit conditions.

reading is the present value. Each successive press of the MAX MIN button circulates the display mode among these options.

To exit the MAX/MIN mode, press and hold the MAX MIN button for one second.

4.5Auto Power Off

To conserve battery power, the instrument will sound a warning tone and automatically shut off 30 minutes after the last switch or button operation.

4.6Low Battery Condition

When the battery voltage is at or below the minimum for proper operation, the symbol will show on the LCD indicating the battery must be replaced. To replace batteries, see Section 6.1.

4.7Fuse Protection

To protect the instrument from excessive input signal levels, the inputs are protected with two fast blow fuses. All inputs except the A (AC or DC Current) input are protected with a 0.5A/250V fuse. The A input is protected with a 10A/250V fuse. To replace fuses, see Section 6.2.

5.0Operating Instructions:

5.1AC Voltage Measurements

WARNING

Maximum Input Voltage is 600VAC. To avoid electrical shock hazard and/or damage to this instrument, do not attempt to make any voltage measurement that may exceed this limit.

1. Connect the red test lead to the ‘V’ jack and the black test lead to the ‘COM’ jack.

2. Set the Function Selector switch to the V~ range.

3. Connect the test leads in parallel with the circuit being measured.

4. Read the measured voltage on the instrument display.
