4215-HS Indicator

Manual

(PM-4101)

Introduction

The Model 4215-HS is a versatile precision instrument intended for the digital readout of strain gage sensors

such as load cells. Optical encoders are also supported.

Features:

* Full bi-polar 6 digit display (±999,999) using two line, 20 character, vacuum fluorescent display for clear, pre

cise indication of measured quantities and limit status.

* No knobs or dials. No internal jumpers. All adjustment and calibration is done using user-friendly front panel

menus. Keylock option to prevent accidental or unauthorized changes to the unit’s setup.

* Measure load in pounds, kilograms, Newtons, PSI, MegaPascals, kilo-pounds, kiloNewtons, metric tons,

mV/V, or grams. User defined base area for PSI and MPa. Tare at any time.

* Capture the load peak and valley, display in pounds, kilograms, Newtons, PSI, MegaPascals, kilo-pounds,

kilo-Newtons, metric tons, or mV/V. Reset at any time.

* Measure position and velocity with optional encoder input. Display in English units, metric units, or in per

cent of a user defined base length. Reset at any time.

* Four contact closure Limit switches. You can set which signal drives the limit (load, peak, valley, position,

or velocity), normally open / normally closed, set point, and manual reset (latched) or automatic reset (not

latched).
