3.2.11 CHANGING MAXIMUM VOLTAGE OR CURRENT VALUE
The default maximum values of voltage and current are determined by the model, e.g., 500V
and 80mA for the BHK 500-80MG. These values can be lowered by the user to prevent inadver-
tent damage to a specific circuit under test by establishing software limits through the use of the
MENU key. Lowering the maximum values of the BHK 500-80MG to 100V and 40mA, effectively
makes the unit a 100V/40mA power supply.
With the power supply in command entry status
(:_:_:)
, press MENU key until the LCD reads
New MAXIMUM Vset
(or
Iset) (=_=_=) n.n
where n.n is the maximum value setting to be
changed (V for voltage, mA for current). Press CLEAR to exit menu without changing setting or
press ENTER to validate existing value. Press number keys to enter new value and press
ENTER to accept new setting (the
key erases data just entered), or CLEAR to exit without
changing setting.
NOTE: Two decimal places are used for voltage settings and three decimal places for current
settings (except that only one decimal place is used for setting voltage on Models BHK
1000-40MG and BHK 2000-20MG).
If a value is entered that is higher than the rated maximum for the power supply, the bottom line
of the LCD flashes

Iset MAX =
where E
O
max or I
O
max is the
rated maximum of the power supply. The unit remains in data entry status
(=_=_=)
waiting for
a value equal to or less than the maximum value. Press CLEAR to exit without changing the
value.
Once the maximum value has been changed, if a value higher than the new maximum is
attempted to be programmed, the LCD flashes
Vset
(or
Iset
)
MAX = n.n
where n.n is the
programmed maximum (V for voltage, mA for current).
NOTE: If the programmed output value is higher than the new maximum value established
with the MENU key, the output will be automatically limited to the new maximum value.
3.2.12 STORING POWER SUPPLY OUTPUT SETTINGS
The programmed settings of voltage, current, overvoltage protection and overcurrent protection
can be stored in one of the 40 memory locations available for local programming (see PAR.
3.2.15).
With the power supply in command entry status
(:_:_:)
, press STORE key. The LCD reads
STORE mem (=_=_=) nn
where nn is the memory location where the settings are to be
stored. Press CLEAR to exit without changing setting. Press ENTER to validate existing loca-
tion or enter memory location (from 1 to 40) and press ENTER. The programmed voltage, cur-
rent, overvoltage protection and overcurrent protection settings in effect when ENTER is
pressed are stored in the selected memory location. To recall stored settings, see PAR. 3.2.13.
The default value at power-up for the Store command is 01. During normal operation, the loca-
tion last used is displayed.
