NIDCPOWER_ATTR_CURRENT_LIMIT_RANGE
Specific Attribute
| Data type |
Access | Applies to | Coercion | High-Level Functions |
|---|---|---|---|---|
| ViReal64 | R/W | N/A | Yes | niDCPower_ConfigureCurrentLimitRange |
Description
Specifies the current limit range, in amps, for the specified channel(s). The range defines the valid value to which the current limit can be set. Use the NIDCPOWER_ATTR_CURRENT_LIMIT_AUTORANGE attribute to enable automatic selection of the current limit range.
The NIDCPOWER_ATTR_CURRENT_LIMIT_RANGE attribute is applicable only if the NIDCPOWER_ATTR_OUTPUT_FUNCTION attribute is set to NIDCPOWER_VAL_DC_VOLTAGE.
The channel must be enabled for the specified current limit to take effect. Refer to the NIDCPOWER_ATTR_OUTPUT_ENABLED attribute for more information about enabling the output channel.
Valid Values:
NI PXI-4110
| 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 |
NI PXI-4130
| Channel | Current Limit Range | Current Limit |
|---|---|---|
| 0 | 1 A | +0.02 to +1 A |
| 1 | 200 μA | +4 to +200 μA |
| 2 mA | +0.04 to +2 mA | |
| 20 mA | +0.40 to +20 mA | |
| 200 mA | +4 to +200 mA | |
| 2 A | +0.04 to +2 A |

Note If a range other than what is listed in the preceding table is selected, it will be coerced to the next-highest range. For example, requesting the 100 mA current limit range on Channel 1 on the NI-PXI 4130 coerces the current level range to 200 mA. Refer to the Ranges topic in the NI DC Power Supplies and SMUs Help for more information about coercion. |
