RP-35A

A Precision Autozeroing

High Input Impedance

Single-Ended

optional Differential input

with Switching AC/DC Power supply

General Features

The Texmate Model RP-35A is a precision, autozeroing when 0V applied, 312 digit meter designed to fit most other manufacturers panel cutouts, in clud ing DIN/NEMA standard. It measures bipolar single-ended and optional differential DC voltages over three user-programmable ranges from 1.999 to 199.9VDC fullscale. For other 4-20 mA, ACV, ACA and DCA applications, the suggested meter in the same case size is the UM-35-PROCESS, UM-35-DCA, UM-35-ACV and UM-35-ACA.

The UM-Series also has temperature and pressure meters that are in the same case size as the RP-35A.

Signal Input Pin

Calibration Procedure

Apply power to the meter. Then with a pre ci sion DC reference source apply +1.900 VDC be tween the Signal High Input Pin 1 and Signal Low Input Pin 3. Adjust SPAN po ten ti om e ter until the display reads +1.900 V. Note: The volt age applied in this case is for a +2.000 V full-scale meter. For other ranges, call factory.

SPAN Potentiometer (Pot)

The SPAN pot is on the right side of the signal input. Typical adjustment is 20% of the input signal range.

Clear Lockable Water-proof Cover

The clear lockable cover is designed to be dust and waterproof to NEMA-4X, IP65 standards. The assembly consists of a base and a cover with a cam hinge and key-lock fastening mechanism. An O-ring, or neoprene gasket forms a seal between the base and the panel. The cam hinge prevents the cover from closing when opened until pushed closed. The cover has a tapered recess that, when closed, forms a seal with a tapered spigot on the base. A key-lock employs a cam locking device to force the spigot into the recess, ensuring seal integrity. A safety catch keeps the cover closed even when the key is removed, and the keyhole can be used to attach a safety seal clip, preventing unauthorized

opening.
