Records time and date stamped DC voltage data. Accepts voltage signals from sensors, transducers and many other common voltage sources. Features user-programmable Engineering Units and offset/gain calculations so input voltages can be scaled to proper units being measured. For example, a flow rate sensor with a voltage output can be displayed as flow rate in the software graph and data. Four different voltage ranges are available. (±100mV model features differential input capability). Eight channel, screw terminal inputs. Voltage Range: ±100mVDC, 0 to 2.5VDC, 0 to 15VDC and 0 to 30VDC Voltage Resolution: See Table Below Calibrated Accuracy: ±100mVDC and 0 to 2.5VDC: ±0.01%FSR at 25°C 0 to 15VDC and 0 to 30VDC: ±0.10%FSR at 25°C Memory: 16,383/channel Sample Rate: 1 second up to 12 hours LED Indicator: Red Channels: 4 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: No Weight: 17oz.
