High Speed Load/Strain Meters and Process/Voltmeters, Dual Differential Inputs Available

The DP7600 is a high speed load/strain meter. The unit performs 1000 conversions per second with limit checking and peak/runout tracking done at a user selectable rate (from 1 to 500 Hz). Peak and runout data can also be displayed using the front panel switches. A tare reading, up to 50% of span, can be entered with a single front panel push button.
The DP7700 is a high speed process/voltmeter with many of the same features. The DP7700 accepts most process inputs from 0-200 mV to 0-10 Vdc and 4-20 mA current loops. Transducer/loop power of ±15 Vdc @ 50 mA is standard.
Programming both meters is accomplished via five switches located on the front panel. The text at the top of the switch (NORMAL, PEAK, RUNOUT, TARE, ABS/REL) indicates its normal function. The text at the lower half of the switch (ENTER, UP, DOWN, NEXT, EXIT) indicates the switch’s function during setup and calibration.
