Product Description Precision Multi Product Calibrator Summary TD1870 is a multi-function calibrator with wide range and high accuracy, integrates AC/DC voltage and current standard source, can output excellent DC\AC voltage, DC\AC current, DC\AC power, phase, frequency, and analog resistance etc. It's applied for calibrating 5.5 digits or less digital multimeters.Features DC voltage output: ±(0 ~ 1020 V)DC current output: ±(0 ~ 20.5 A)AC voltage output: 1 mV ~ 1020 VAC current output: 29 μA ~ 20.5 ASinusoidal wave frequency: 10 Hz ~ 500 kHzSimulated DC resistance: 0 Ω ~ 1100 MΩ2 MHz square wave frequency outputPhase output AC/DC power output Thermocouple output(optional)Thermal resistance output(optional)Clamp meter calibration (optional) Application Characteristics ☆ Front panelItemDescription1LCD touchable screen.2Operation panel.3Pulse frequency output terminal.4Simulated DC resistance, RTD, Auxiliary voltage output terminals.5Simulated capacitance output terminals.6AC/DC voltage output terminals.7Thermocouple output terminals.8AC/DC current output terminals. ☆ Rear\Side PanelItemDescription1Handle: used for carrying instruments2Foldable feets3USB/LAN/RS2324AC 220V power interface5power switch6Chassis ground binding post7Cooling vents ☆ Wide output range ☆ 4-terminals Simulated DC resistance2-terminals and 4-terminals resistance wiring mode. When calibrating the low value resistance, the four wire system wiring mode can effectively eliminate the measurement error caused by the resistance of the test lead and improve the measurement accuracy.Compared with the standard physical resistance box, the analog resistance output has the following characteristics: a. Continuously adjustable, with better adjustment fineness and sensitivity. b. Smaller size and lighter weight. c. No influence of transfer switch error, residual resistance error and contact resistance error. ☆ Multiple output\adjustment methods"Direct output" mode: the value output can be set directly by physical key or touch screen.
