Front Panel Operation - 5

Metering Keys

Metering keys control the metering functions of the dc source. As set from the factory, all front panel

measurements are calculated from a total of 2048 readings taken at a 46.8 microsecond sampling rate.

Therefore, the factory default acquisition time for a single front panel measurement is about 100

milliseconds. Refer to “Making Front Panel Measurements” for more information about changing the

front panel sampling rate and the number of measurement points.

NOTE: The front panel sample rate and data point settings are separate and independent of the

sample rate and data point settings that are programmed over the GPIB interface. When

an GPIB measurement is in progress, the front panel display temporarily indicates

-- -- -- -- --. Front panel measurements resume when the GPIB measurement completes.

GPIB measurements are discussed in chapter 7.

Press this key to access the meter menu list. Also use this key to exit a menu at

any time and return to meter mode.

Display Measurement

<reading>V <reading>A Measures output dc voltage and current

<reading>V MAX Measures peak output voltage

<reading>V MIN Measures minimum output voltage

<reading>V HIGH Measures the high level of a voltage pulse waveform

<reading>V LOW Measures the low level of a voltage pulse waveform

<reading>V RMS Measures rms voltage

<reading>A MAX Measures peak output current

<reading>A MIN Measures minimum output current

<reading>A HIGH Measures the high level of a current pulse waveform

<reading>A LOW Measures the low level of a current pulse waveform

<reading>A RMS Measures rms current

Press this key to access the following metering functions.

Display Command Function

CURR:RANGE <char> Select current range (AUTO, LOW or HIGH)

CURR:DET <char> Select current measurement bandwidth (ACDC or DC)

TINT <value> Sets the front panel measurement interval in seconds
