3.2.9 DATA ENTRY Keys (Numerical Data Input)
The DATA ENTRY keys are used to change the voltage source value, current source value, limit values
and other numerical parameters.
0 to 9 keys: Enter numerical data 0 to 9
.key: Enters a decimal point
+/- key: Sets polarities +/-
Rotary knob: Changes the prefix of numerical data (p, n, , m, k, M, etc.).
CE key: Cancels input data at data setting.
BS key: Deletes the last character of input data.
ENTER key: Confirms input data and stores the parameter.
EXIT key: Cancels numerical data input.
Returns to the previous value and releases the edit status.
3.2.10 OPR Key/SUSPEND Key (Operate/Suspend)
OPR key: Switches the output status between Operate and Suspend.
Pressing this key in the Standby or Suspend status will switch to the Operate status.
In the Operate status, the output turns ON and the OPR key is lit.
Pressing this key in the Operate status will switch to the Suspend status.
In the Suspend status, suspend voltages are output without turning OFF the output relays.
The OPR key flashes.
SUSPEND key (shift mode):
The Suspend status is selectable between HiZ (high impedance status) and LoZ (low
impedance status).
Fore more information, refer to Section 4.2.4.6, “Operate, Standby and Suspend.”
WARNING: Beware of electrical shock! In the Operate status (output relay ON), hazardous volt-
age may occur depending on the settings.
3.2.11 STBY Key (Output Standby)
The STBY key is used to turn OFF the output relays to set Standby status. The OPR indicator goes OFF.
NOTE: Whenever switching between Operate and Standby, the output relays are turned on and
off every time. To extend the relay life spans, using the Suspend function that switches
between Operate and Suspend is recommended.
