Records time and date stamped DC current data from external sensors, transducers and many other sources. Features user-programmable Engineering Units and offset/gain calculations so input signals can be scaled to proper units being measured. For example, a water meter with a 4-20mA output can be displayed as liters or gallons, etc., in the software graph and data. Negative current signals can be monitored and recorded, for a broad range of applications. Three different DC current ranges are available. 8 Channels. Screw terminal inputs. Current Range: ±1mA ±25mA ±100mA Resolution: ±1mA: 0.05ìA ±25mA: 1ìA ±100mA: 5ìA Calibrated Accuracy: ±1mA: ±0.5%FSR at 25°C ±25mA and ±100mA: ±0.1%FSR at 25°C Input Impedance: ±1: 50Ù ±25mA: 10Ù ±100mA: 2Ù Channels: 8 Memory: 16,383 readings per channel Sample Rate: 1 second up to 12 hours LED Indicator: None Required Interface Package: IFC110 Baud Rate: 2,400 Typical Battery Life: 1 year Operating Environment: -20~+60°C, 0~95%RH non-condensing Material: Anodized aluminum Dimensions: 3.5" x 4.4" x 1.5" (89mm x 112mm x 39mm) CE Approval: Yes Weight: 17oz.
