Other measurements

49. STELR Ranging Multimeter
There are other settings on the multimeter that can be used for testing frequency, capacitance, transistors and diodes.
These are not required for use as part of the STELR program, but may be of general use in other programs.
For detailed instructions on the use of these settings, please refer to the Digital Multimeter Operator’s Manual sheet included with the multimeters.

Hold button

55. When using the wind turbine, a fluctuating current is measured.
STELR Ranging Multimeter
When using the wind turbine, a fluctuating current is measured.
This is a result of the variable wind flow from the fan.
Pressing the hold button, ‘freezes’ the reading.
Pressing the hold button a second time returns the meter to the variable measurements.
Students can be encouraged to take three readings, five or 10 seconds apart, and average them for a more accurate measurement.

56. STELR Ranging Multimeter
Press hold button to ‘freeze’ the reading. Press again to ‘unhold’ the display.

58. STELR Ranging Multimeter
Press and hold the ‘hold’ button for two seconds until it beeps, and the screen will light up

59. Press again to turn off the backlight.
STELR Ranging Multimeter
Press again to turn off the backlight.
It is recommended that use of the backlight button is minimised, as it tends to drain the battery quite quickly.
