5.3.5 Instrument
To measure Ampere Hour (Ah), Watt Hour (Wh), minimum/maximum output current or power, an internal
instrument can be enabled.
The sampling interval is 100ms.
Ampere Hour Instrument
To enable the current measurement instrument:
Syntax: MEASure:INStrument<sp>AH,STATE,<boolean><term>
(Re)enabling the instrument will reset all previous measurements.
To read the enable status:
Syntax: MEASure:INStrument<sp>AH,STATE?<term>
To read the time the instrument is active:
Syntax: MEASure:INStrument<sp>AH,TIMEHR?<term>
The result will be in hours with three decimals.
If the instrument is not enabled, the result will be zero.
Syntax: MEASure:INStrument<sp>AH,TIMESEC?<term>
The result will be in seconds with one decimal.
If the instrument is not enabled, the result will be zero.
To read the total Ampere Hour for the positive current:
Syntax: MEASure:INStrument<sp>AH,POS,TOTAL?<term>
The result will be in Ampere Hour (Ah), scientific notation.
If the instrument is not enabled, the result will be zero.
To read the total Ampere Hour for the negative current:
Syntax: MEASure:INStrument<sp>AH,NEG,TOTAL?<term>
The result will be in Ampere Hour (Ah), scientific notation.
If the instrument is not enabled, the result will be zero.
To read the minimum positive current during the time the instrument is enabled:
Syntax: MEASure:INStrument<sp>AH,POS,IMIN?<term>
The result will be in Ampere. If the instrument is not enabled, the result will be zero.
To read the maximum positive current during the time the instrument is enabled:
Syntax: MEASure:INStrument<sp>AH,POS,IMAX?<term>
The result will be in Ampere. If the instrument is not enabled, the result will be zero.
To read the minimum negative current during the time the instrument is enabled:
Syntax: MEASure:INStrument<sp>AH,NEG,IMIN?<term>
The result will be in Ampere. If the instrument is not enabled, the result will be zero.
To read the maximum negative current during the time the instrument is enabled:
Syntax: MEASure:INStrument<sp>AH:NEG,IMAX?<term>
The result will be in Ampere. If the instrument is not enabled, the result will be zero.
Watt Hour Instrument
To enable the power measurement instrument:
Syntax: MEASure:INStrument<sp>WH,STATE,<boolean><term>
Enabling the instrument will reset all previous measurements to zero.
To read the enable status:
Syntax: MEASure:INStrument<sp>WH,STATE?<term>
To read the time the instrument is active:
Syntax: MEASure:INStrument<sp>WH,TIMEHR?<term>
The result will be in hours with three decimals.
If the instrument is not enabled, the result will be zero.
Syntax: MEASure:INStrument<sp>WH,TIMESEC?<term>
The result will be in seconds with one decimal.
If the instrument is not enabled, the result will be zero.
To read the total Watt Hour for the positive power:
Syntax: MEASure:INStrument<sp>WH,POS,TOTAL?<term>
