channel is determined automatically by the main channel selected. When Voltage mode is
selected, the current protection limit channel is active, and when Current mode is selected, the
Voltage protection limit channel is active.
3.5.3 PROGRAMMING VOLTAGE OR CURRENT AND ASSOCIATED PROTECT LIMITS
When the operating mode is Voltage mode, use the VOLT command (see PAR. B.86) where
= digits with decimal point and Exponent, e.g., 2.71E1 for 27.1. For example, send
VOLT 2.71E1 to set output voltage to 27.1 Volts in voltage mode.
When the operating mode is Current mode use the CURR command (see PAR. B.86) where
= digits with decimal point and Exponent, e.g., 5.2-E1 for 0.52. For example, send
CURR 5.2-E1 to set output current to 0.52A in current mode.
3.5.4 PROGRAMMING ASSOCIATED PROTECT LIMITS
3.5.4.1 WHEN OPERATING IN VOLTAGE MODE
When the operating mode is Voltage mode, the following parameters are in effect (see Table 3-2
for definitions): +Voltage Max, –Voltage Min, +C Protect Max, +C Protect Min, –C Protect Max, –
C Protect Min, ±C Protect.
+Voltage Max and –Voltage Min are programmed using the VOLT:LIM commands (see PAR’s.
B.88 through B.93 for details). These commands limit the maximum ±voltage that can appear at
the output.
+C Protect Min and –C Protect Max cannot be programmed and are automatically set to mini-
mum (box).
+C Protect Max and –C Protect Min. are programmed using the CURR:PROT:LIM commands
(see PAR’s. B.37 through B.42 for details.) These commands define the maximum values that
±current protection (±C Protect) can be set to. If the programmed values are exceeded, a com-
mand error -201, “Current range error” occurs.
+C Protect and –C Protect are programmed using the CURR:PROT commands (see PAR’s.
B.29 through B.36 for details.) These commands program the ±current protection values. If load
current reaches the ±current protection values, current will be clamped so ±current protection
values cannot be exceeded.
3.5.4.2 WHEN OPERATING IN CURRENT MODE
When the operating mode is Current mode, the following parameters are in effect (see Table 3-
2 for definitions): +Current Max, –Current Min, +V Protect Max, +V Protect Min, –V Protect Max,
–V Protect Min, ±V Protect.
+Current Max and –Current Min are programmed using the CURR:LIM commands (see PAR’s.
B.88 through B.93 for details). These commands limit the maximum ±current that can appear at
the output.
+V Protect Min and –V Protect Max cannot be programmed and are automatically set to mini-
mum (box).
+V Protect Max and –V Protect Min. are programmed using the VOLT:PROT:LIM commands
(see PAR’s. B.37 through B.42 for details.) These commands define the maximum values that
