3.3 INST ALLA TION/REMOVAL The TX82B is housed in a 1/8 DIN case. The electronic circuitry can be installed or removed from the front and is attached to the case with two M4 screws through the rear panel. Panel Mounting 1. Remove the two thumbnuts on the rear of the case. 2. Slide the sleeve off the case (see Figure 3-1 Exploded View). 3. V erify t[...]

7 5.0 CONFIGURA TION The standard TX82B meter is factory-configured for an input of 4-20 mA to display 00.0 to 100.0. Field configuration for input current range, decimal point location, dummy right-hand zero digit, coarse zero range selection, and reverse span slope may be done by relocating internal push-on jumpers and adjusting the span and zero[...]

9 6.0 CUSTOMER CONFIGURA TION AND CALIBRA TION Use this procedure to determine the configuration of the TX82B customized setup. The procedure is general; customers can specify any two current inputs and their corresponding digital readings. Pin-groups are shown in Figure 5-1. 6.1 FORMULA Base all your calculations on either the 1-5, 4-20 or 10-50 m[...]

10 6.2 CONFIGURA TION PROCEDURES 1. Remove all push-on jumpers. 2. For an input current range of 1-5 mA, no jumper is required. For 4-20 mA input, install a push-on jumper at S1-H. For 10-50 mA input, install a push-on jumper at S1-J. 3. If N2 (Section 6.1) is less than N1, reverse the signal polarity by removing jumpers from S1-B and S1-C and rein[...]
