Capacitance Measurements; Frequency And Duty Ratio Measurements; Type K Temperature Measurements - FLIR Extech Instruments MA1500 Manual

Capacitance Measurements

WARNING: To avoid electric shock, discharge the capacitor before measuring.
1. Set the function switch to the CAP position.
2. Insert the black test lead banana plug into the negative COM jack.
Insert the red test lead banana plug into the positive
3. Press the MODE button to select capacitance (μF) measurements.
4. Touch the black test probe tip to one side of the device.
Touch the red test probe tip to the other side of the device.
5. Read the capacitance value in the display.
Note: For very large values of capacitance measurement time can be several seconds before the
final reading stabilizes.
Note: The Zero feature removes stray test lead capacitance to improve the accuracy of low value
capacitance measurements. Press the ZERO button and the display will zero. The offset
value is now stored and is subtracted from all measurements.

Frequency and Duty Ratio Measurements

1. Rotate the function switch to the Hz % position.
2. Insert the black test lead banana plug into the negative COM jack.
Insert the red test lead banana plug into the positive Hz jack.
3. Touch the black test probe tip to one side of the device.
Touch the red test probe tip to the other side of the device.
4. Read the Frequency value on the upper large display.
Read the Duty Ratio on the lower small display.

Type K Temperature Measurements

1. Rotate the function switch to the Temp position.
2. Press the °F/°C button to select °F or °C.
3. Plug the type K probe into the COM and TEMP jacks using the mini-plug to banana pug
adaptor provided. Make sure that the positive and negative terminals are connected correctly.
4. Connect the temperature probe tip(s) to the object which will be tested.
5. Read the temperature on the display.
Note: In case of an open input or a temperature overrange, the meter will display "- - - - -" .
Data Hold
To freeze the LCD reading, press the HOLD button (located on the function switch knob). While
data hold is active, the HOLD icon appears on the LCD. Press the HOLD button again to return to
normal operation.
