Scale Basic 4.2E Reference
Next1 (see Loop1 / Loop2 instruction) 246
Next2 (see Loop1 / Loop2 instruction) 248
Nop 254
Purpose: no-operation, this instruction does nothing.
Remarks: rarely used in scale basic.
Example:
Nop No-operation, do nothing
Prompt (nnn) (nnn) (nnn)… 232 [nnn] [nnn]…[0]
Purpose: display a message on the numeric display.
Remarks: this instruction is used to display status or to prompt the user for data input. If the Get
data instruction immediately follows the Prompt instruction, then the prompt is used for data
input. NOTE: user all capital letters. Most cap’s will display legibly, lower case characters
will not display legibly. The following upper case characters will not display: K, M, Q, V,
W, X.
Example: prompt the user for target weight using the prompt “SETPT”.
Prompt, “SETPT” display “SEtPt” on the display
Get data, Memory1 get setpoint data.
An alternative method to prompt for data uses a time delay to display the prompt, then the
Get data instruction uses it’s default “ENTER” prompt. Assume Timer 1 is configured for 1
second delay:
Prompt, SETPT display “SEtPt on the display
Timer on, 1 turn on timer 1 (1 seconds delay).
Loop1 While timer 1 on
If, Timer1 <keep looping>
Next1
End if End while
Get data, Memory1 get setpoint. Prompt is replaced by “EntEr”.
End End of function
Relay off / Relay on (relay no.) 223 [n] / 222 [n]
Purpose: to turn off / on relay outputs.
Remarks: the TTL output signals are labeled Relay1, Relay2, …. The Relay off instruction sets
the TTL output signal to TTL high, the Relay on instruction sets the TTL output signal to
TTL low. When the TTL output is connected to a solid state relay, the TTL low level turns
ON the relay.
NOTE1: Relay off, 0 turns off all relays.
NOTE2: Relay on/off, 10 gets relay number from register 10. For example
Set Memory10, 4 set memory10 = 4
