seconds. The LCD annunciators will start to cycle when the CVC is turned
off. Release the ON/OFF button as soon as the display starts to cycle or the
unit will turn on again.
SELECTING OUTPUT MODE
as shown below. If the test leads are plugged into the mA XMTR or mA
OUTPUT jack, or no leads are plugged in, “mA” will turn on. If the load
resistance is too high or the leads are left open, “OVERLOAD” will turn
on. If the leads are plugged into the VOLTS OUTPUT jack, “V” will turn
on. If the load resistance is too low or the leads are shorted, “mA” may
stay on or turn on.

Fig 3. Simulate a 2-Wire mA Transmitter Loop With External 12 to
30V DC Supply. A similar connection can be used to extend output
range of CVC beyond 300 ohms. A 24V source will allow CVC to source
into an impedance of >1000 ohms.
