2-18 Basic Power Supply Operation
Command notes (measure V and I, and DVM input)
SENSe[1]:FUNCtion <name> Applies to battery channel (#1)
SENSe2:FUNCtion <name> Applies to charger channel (#2)
1. The parameter name can instead be enclosed in single quotes (e.g., ‘CURRent’).
2. With “DVMeter” selected, the instrument measures the voltage applied to the input of
the digital v
oltmeter (DVM).
3. The “PCURrent” and “LINTegration” parameters for :FUNCtion (which are not listed
in Table 2-4) select the pulse current and long integration measurement modes. These
measurement modes are covered in Sections 3 and 4, respectively.
SENSe[1]:AVERage <NRf> Applies to battery channel (#1)
SENSe2:AVERage <NRf> Applies to charger channel (#2)
1. When requesting a single reading (FETch?, READ?,
or MEASure?), average count
specifies the number of measurement conversions to average for the reading. For
example, with the average count set to 10, READ? will trigger 10 measurement
conversions and return (and display) the average of those 10 conversions for the battery
channel. When requesting an array of readings (FETCh:ARRay?, READ:ARRay? or
MEASure:ARRay?), average count specifies the number of measurements to place in an
array. For example, with the average count set to 10, READ:ARRay? will trigger and
return 10 battery channel readings (charger channel command similar).
2. Signal oriented measurement commands (e.g., READ?) are covered in Section 9.
Independent voltage measurements (DVM)
The power supply has an independent digital voltmeter (DVM) that can measure up to
+30VDC and down to -5VDC. Connections for the DVM are shown in Figure 2-1.
DVM input display mode
The DVM input display mode must be selected in order to measure voltage applied to DVM
input of the power supply. This display mode is selected as follows:
NOTE T
o display measured readings if the instrument is in the settings mode, press the SET
key until the blinking stops (the measured readings can then be displayed). To deter-
mine if the instrument is in the settings mode, check for a blinking cursor in a digit of
the volta
ge or current field (if present, the instrument is in the setting mode).
1. Press the DISPLAY key to access the display menu. DISPLAY TYPE #1 (battery chan-
nel active) or DISPLAY TYPE #2 (charger channel
active) will appear on the top line of
the display. Use
▲
or
▲
keys to toggle the active channel.
2. Press the
▲ or ▼ key until “DVM INPUT” is displayed.
3. Press ENTER.
NOTE F
or details on display modes, see “Display modes” in Section 1.
