For voltage output testing, connect the positive and negative terminals to the analog input of your PLC or test device. For current loop testing, connect the SG-002 in series with the load (typically 250 ohm resistor for 4-20mA loops), ensuring the current path is complete. Power on the unit and allow 2-3 minutes for thermal stabilization before beginning precision measurements.\u003c\/p\u003e\n\n\u003cp\u003eAdjust the voltage potentiometer smoothly across its full range while observing the corresponding readings on your PLC analog input display or external multimeter. Start at the minimum position and slowly increase to maximum, noting any non-linearity or dead zones that indicate signal conditioning problems. For current mode testing, set the potentiometer to generate the desired milliamp value and verify the output using a multimeter in series with the load. Repeat the test across multiple points (0%, 25%, 50%, 75%, 100%) to confirm linearity and identify any scaling errors in the PLC input module configuration. Document all readings for compliance records and system commissioning reports.\u003c\/p\u003e\n\n\u003ch2\u003eFrequently Asked Questions\u003c\/h2\u003e\n\n\u003cdetails\u003e\n\u003csummary\u003eCan the SG-002 generate 4-20mA signals for standard industrial transmitters?\u003c\/summary\u003e\n\u003cp\u003eYes, the SG-002 0-24mA output range covers the standard 4-20mA industrial loop range. Simply adjust the potentiometer to the 4mA position for zero signal and 20mA for full scale. This makes it ideal for simulating pressure, temperature, and flow transmitters during PLC testing without requiring actual field sensors.\u003c\/p\u003e\n\u003c\/details\u003e\n\n\u003cdetails\u003e\n\u003csummary\u003eWhat is the difference between voltage mode and current mode output?\u003c\/summary\u003e\n\u003cp\u003eVoltage mode (0-12V) is used for testing analog inputs that measure voltage directly, such as 0-10V sensor outputs or analog potentiometer inputs. Current mode (0-24mA) is used for 4-20mA loop testing where the signal is transmitted as a current through a series circuit. The SG-002 provides both simultaneously, allowing you to test multiple input types on the same device without reconfiguration.\u003c\/p\u003e\n\u003c\/details\u003e\n\n\u003cdetails\u003e\n\u003csummary\u003eIs galvanic isolation important for PLC testing?\u003c\/summary\u003e\n\u003cp\u003eYes, galvanic isolation prevents ground loop currents that can introduce measurement errors of 1-5% in sensitive analog circuits. When testing multi-module PLC systems or networked panels, ground loops can cause false readings and mask real signal conditioning problems. The SG-002 isolation ensures accurate test results that reflect actual sensor behavior without ground-induced noise.\u003c\/p\u003e\n\u003c\/details\u003e\n\n\u003cdetails\u003e\n\u003csummary\u003eCan I use the SG-002 for long-duration stress testing?\u003c\/summary\u003e\n\u003cp\u003eThe SG-002 is designed for field commissioning and troubleshooting applications requiring intermittent use. For extended stress testing lasting hours, ensure adequate ventilation around the unit and monitor for thermal drift. The temperature stability specification of ±0.05% per degree Celsius means that in a 40-degree temperature rise, accuracy may drift by 2%, which is acceptable for most industrial testing but should be noted in precision calibration work.\u003c\/p\u003e\n\u003c\/details\u003e\n\n\u003cdetails\u003e\n\u003csummary\u003eWhen will I receive my order?\u003c\/summary\u003e\n\u003cp\u003eOrders are dispatched within 1-5 business days from our Bengaluru warehouse.
