∙Channel Scanning

Can be continuous scanning, scanning at an interval time, single scans, or triggered (internal or external) scans.

∙Channel Monitoring

Make measurements on a single channel and view these measurements on the display.

∙Channel Scanning and Monitoring

View measurements made for the monitor channel while scanning of all active channels continues.

∙Multi-Function Display

Left (numeric) display shows measurement readings; also used when setting numeric parameters.

Right (alphanumeric) display used for numeric entries, channel number selection and display, status information, and operator prompts.

∙Front-Panel Operation

Almost all operations can be readily controlled with the buttons on the front panel.

∙Measurement Input Function and Range

Volts dc (VDC), volts ac (VAC), frequency (Hz), and resistance (Ω) inputs can be specified in a fixed measurement range. Autoranging, which allows the instrument to use the measurement range providing the optimum resolution, can also be selected.

∙Temperature Measurement

Thermocouple types J, K, E, T, N, R, S, and B, and Hoskins Engineering Co. type C are supported. Also, DIN/IEC 751 Platinum RTDs are supported.

∙Totalize Events on the Totalizing Input

∙4-Terminal Resistance Measurements (Channels 1 through 10 only)

∙RS-232 Computer Interface Operation

∙Measurement Rate Selection

∙Nonvolatile Memory

Storage of minimum, maximum, and most recent measurements for all scanned channels. Storage of Computer Interface setup, channel configurations, and calibration values.

Storage of measurement data: storage for 2047 scans of up to 21 channels, representing up to 42,987 readings (Hydra Data Logger only).
