NI-DCPower (English | Japanese)

The measurement range is implicitly selected based on the configured output range. Thus, you cannot change the measurement range independently of the output range. The selected measurement range is large enough to measure any voltage or current within the configured output range.

When the output function is set to NIDCPOWER_VAL_DC_VOLTAGE using the niDCPower_ConfigureOutputFunction function or DC Voltage using the niDCPower Configure Output Function VI, the following ranges are used.

Channel Voltage Level Range Voltage Level
0 6 V 0 to +6 V
1 20 V 0 to +20 V
2 20 V 0 to -20 V


Channel Current Limit Range Current Limit
0 1 A +0.01 to +1 A
1, 2 20 mA +0.20 to +20 mA
1 A +0.01 to +1 A

When the output function is set to NIDCPOWER_VAL_DC_CURRENT using the niDCPower_ConfigureOutputFunction function or DC Current using the niDCPower Configure Output Function VI, the following ranges are used.

Channel Current Level Range Current Level
0 1 A +0.01 to +1 A
1 20 mA +0.20 to +20 mA
1 A +0.01 to +1 A
2 20 mA -0.20 to -20 mA
1 A -0.01 to -1 A


Channel Voltage Limit Range Voltage Limit
0 6 V 0 to +6 V
1, 2 20 V 0 to +20 V


Note Note  If a range other than what is listed in these tables is selected, the range is coerced to the next-highest range. For example, requesting the 100 mA current level range on Channel 1 on the NI-PXI 4110 coerces the current level range to 1 A. Refer to the Ranges topic for more information about coercion.

Overranging

Enabling overranging for a particular channel extends current and voltage output capabilities from 100% to 105% and current capabilities down from 2% to 1% for the output range. Overranging is applicable to output ranges only and does not apply to measurement ranges. Measurements in any given range may be made up to 105% of the range by default without enabling overranging.

An auxiliary power supply providing at least 12 V at the input terminals should be used when enabling overranging for channel 1. Refer to Ranges for more information about enabling or disabling overranging for a particular channel.

Caution Caution  If the current range is changed while the NI PXI-4110 is in constant current mode, then a spike in the output current could occur for a maximum of 3 ms. This will not occur if the NI PXI-4110 is in constant voltage mode.
