5. The engineering unit for frequency is Hz.
Example:
FREQ 50.0, to set frequency is 50.0Hz.
FREQ 60.0, to set frequency is 60.0Hz.
FREQ 0.1, to set frequency is 0.1Hz, that is to set DC.
VOLTAGE Limit
Purpose:
To set the upper/lower limit value of threshold voltage.
Command Syntax:
All Modules:
LIM:VOLT:{HIGH|LOW}{SP}{NR2}{;|NL}
Description:
This command is to set the upper/lower limit value of threshold voltage. When input voltage
is lower than the lower limit value or higher than the upper limit value, NG indicating light will
come on to indicate “NO GOOD."
Example:
LIM:VOLT:LOW 1.0 ; To set the lower limit value of threshold voltage to 1.0 V.
LIM:VOLT:HIGH 200.0 ; To set the upper Limit vale of threshold voltage to 200.0V.
CURRENT Limit
Purpose:
To set the upper/lower limit value of threshold current.
Command Syntax:
All Modules:
LIM:CURR{HIGH/LOW}{SP}{NR2}{;|NL}
Description:
This command is to set the lower limit value of threshold current. When load sink current is
lower than this lower limit value or higher than the upper limit value, NG indicating light will
come on to indicate “NO GOOD."
Example:
LIM:CURR:LOW:0.05 ; To set the lower limit value of threshold current to 0.05A.
LIM:CURR:HIGH:10.0 ; To the upper limit value of threshold current to 10.0A.
POWER Limit
Purpose:
To set the upper/lower limit value of threshold power (W).
Command Syntax:
LIM:POW:{HIGH|LOW}{SP}{NR2}{;|NL}
Description:
This command is to set the upper/lower limit value of threshold power (WATT). When power
(WATT) is lower than this lower limit value or higher than the upper limit value, NG indicating
light will come on to indicate “NO GOOD."
Example:
LIM:POW:LOW 0.05 ; To set the lower limit value of threshold power (W) to 0.05 W.
LIM:POW:HIGH 250.0 ; To set the upper limit value of threshold power(W) to 250.0 W.
