Use 8 to 10:, 2 watt wire-wound potentiometer. The appropriate shunt should be selected from accessory section and ordered separately. To select the proper shunt, first obtain the fullload current rating of your motor from the name plate, manufacturer's specifications of N.E.C. listing. Multiply that rating by 1.25 and select and order the shunt with an amps rating as large or slightly larger than the calculated value. Installation and calibration instructions are included with the meter. Note 2: AC load meters must be used with external donut transformers. Complete instructions for proper selection are included with each AC load meter. Advance assistance in selecting the appropriate transformer and determining the correct primary/secondary turns ratio can be obtained from a Simpson technical service representative or authorized service center. 4-2 20mA Process Meters Size 3-1/2" 4-1/2" Scale 0-100% 0-100% Model 1327 1329 Catalog No. 35025 35026 Frequency Meters, Self-Shielding Movement Range 45-55 Hz 55-65Hz 380-420 Hz 45-55 Hz 55-65Hz 380-420 Hz Voltage 120V 120V 120V 240V 240V 240V Model/Size and Catalog Number 2-1/2" 3-1/2" 4-1/2" Model 1287 Model 1387 Model 1389 35100 35106 35112 35102 35108 35114 35104 35110 35116 35101 35107 35113 35103 35109 35115 35105 35111 35117
