Resistance Measurement; Continuity Test; Frequency (Hz) Measurement; Relative Reading Measurements - Elma Instruments CM01A User Manual

3.5 Resistance Measurement

3.5.1. Set the rotary switch at Ω.
3.5.2. Insert the test leads into the input jack.
3.5.3. Connect the test prods of the test leads to the two ends of the
resistor or
circuit to be measured.
3.5.4. Read the measured value from the LCD display.

3.6. Continuity Test

3.6.1. Turn the rotary switch to Ω position and move the sliding switch to
AC
position.
3.6.2. Insert the test leads into the input jack.
3.6.3. Connect the test probes of the test leads to the two ends of the
resistor or
circuit to be measured.
3.6.4. Read the measured value from the LCD display.
3.6.5. If the resistance is lower than 40Ω, a beeping sound shall be
heard.

3.7. Frequency (Hz) Measurement

3.7.1. Set the rotary switch at Hz.
3.7.2. Insert the test leads into the input jack.
3.7.3. Connect the test prods of the test leads in PARALLEL to the signal
or
circuit to be measured.
3.7.4. Read the measured value from the LCD display.

3.8. Relative Reading Measurements.

The zero button also can be used to make a relative measurement.
Once the
Button is pushed, the current reading is set to zero and a zero symbol
shall be
displayed on LCD. All the subsequent measurement shall be displayed
as a
relative value with respect to the value being zeroed. Press the zero
button for
2 seconds to return to normal mode. But this function is disabled if
MAX/MIN
function is enabled. Please watch for symbol displayed on LCD.

3.9. Holding the LCD Reading

Press the HOLD button, then the reading will be hold and kept on LCD.
