HANDHELD-PORTABLE ANALOG
SIGNAL GENERATOR
MODEL ASG
TM
DESCRIPTION
The Model ASG is a handheld, battery- or plug-in power
supply powered, pocket-size analog signal generator. It
generates a 0-10 VDC signal in increments of 1V or a 0-
20 mA signal in increments of 2 mA. The LED bar graph
visually indicates analog signal level. The Model ASG can
also continuously ramp to user-defined minimum or maxi-
mum values with user- defined ramp-time settings.
FEATURES
• Powered by 9V battery or plug-in power supply
• Pocket size
• Bar graph LED for signal display
• 0-20 mA (2 mA increments)
• 0-10 VDC (1 VDC increments)
• Ramp function to minimum and maximum values
• Variable ramp function timing
• Low battery indication
• User-defined auto shutoff times for battery
conservation
• Separate milliamp and voltage output jacks
• 6' (1.83m) leads with alligator clips
• Up to 30 hours continuous use on a single battery
• Perfect for loop-powered circuits and externally
powered circuits

Adjusting the ASG is accomplished through buttons 1 through 4 on the front and verified through the LEDs on the
top of the ASG.
Analog Outputs
The ASG has three individual outputs-mA source, two-wire transmitter, and voltage output. The voltage output oper-
ates over a 0-10 VDC range. The "mA Source Output" will source a 0-20 mA signal powered by the battery sup-
plied with the ASG. The output labeled "mA two wire xmitter" requires an external power supply and is intended for
loop powered circuits.
Display
The LEDs on the top of the ASG verify the progress of all adjustments and indicate status of various functions of the
ASG.
The "Status LED" indicates normal operation, low battery, and ramp mode. When this LED is in the off state, it indi-
cates that the ASG is working normally. If the "Status LED" is lit continuously during normal operation, the battery is
low. The "Status LED" will blink whenever the ASG is in a ramping mode.
The "mA Over Load LED" will light whenever the circuit exceeds 300Ω. Note: This "Over Load LED" will light if the
leads are not connected to a device due to an open circuit.
The "Output LEDs" indicate the analog signal level, ramp times duration and programming, and auto off times. The
"Signal Level LEDs" are read as either mA or voltage with the appropriate scale. During ramping mode calibration,
the mA scale is used to represent time in seconds. For instance, 2 represents 2 seconds and 20 represents 20 sec-
onds. During the auto-off change mode the mA scale represents time in minutes. (See Auto-Off Function on page 4)

The Ramping Function
The ASG will continuously ramp between two user-defined endpoints for a user-specified interval time between
each incremental step. The ASG is preprogrammed to ramp between 4 mA (2 VDC) and 20 mA (10 VDC) in 10-
second increments; however, custom incremental times and end points can be temporarily programmed into the
ASG.
ACTION INSTRUCTION VERIFICATION
Set Starting Point Press buttons #1 or 4 to Appropriate "Output LED"
desired starting output level will light
(Figure 3a)
Start Ramping Press and hold buttons #2 & 3 "Status LED" and "Output
(Figure 3b) LED" will blink alternately
Stop Ramping Press buttons #2 & 3 "Status LED" will stop blinking &
(Figure 3c) turn off, "Output LED" will light
continuously
