Compact Instrument sleep current test

The sleep current of the instrument can be tested to determine if the electronics are damaged. Ensure the instrument is not logging before you begin.

Remove the housing and battery (Fig. 1) . Connect the instrument to a power source and an ammeter in series (Figs. 2 and 3). 

Attach the positive connection to the tab where the positive end of the battery would be.

Attach the negative or ground connection to the negative battery tab.

Use an input voltage of 3.6V. 

Typically, a current of less than 10 microamps (μA) is expected. If the current is significantly higher than 10μA, there is likely an issue with the instrument. Contact us at support@rbr-global.com for advice.
