This section briefly describes how to set key parameters effective for accurate and
reliable charge measurement.
Automatic Discharge
The automatic discharge function is effective for preventing the coulomb meter
from range overflow. If this function is enabled, the coulomb meter resets the
charge when the charge reaches the specified level. After resetting, the charge
measurement restarts.
This function is enabled/disabled by pressing the System Menu > Config >
Measure > Coulomb > Auto Dis. function keys. This softkey label shows the present
setting ON (enable) or OFF (disable).
The discharge level can be selected from 2 nC, 20 nC, 200 nC, or 2 C by pressing
the System Menu > Config > Measure > Coulomb > Dis. Level function keys. This
softkey label shows the present setting.
Measure Coulomb
Press the RANGE function key to change the ranging mode, auto or fixed. Where,
the softkey label shows the present measurement range setting, AUTO or fixed
range value.
Measurement range can be set by using the following navigation keys.

measurement is performed once.
Press the Run/Stop key to start a repeat (continuous) measurement. Charge
measurement is performed repeatedly. Minimum measurement interval is 10
