An OMEGA Te c h n o lo g ie s Co m p a n y DP18 Series Model DP18-RT1 True RMS Ammeter .................................................................................................................................................................................................................................................................................................................................................................................................................................................................................................................................... M2107/1294 INSTRUCTION SHEET True RMS Ammeter for current transformer X/5 3 .DIGITS AC AMMETER, TRUE-RMS VALUES, WITH SELECTABLE RANGES ON THE SIGNAL CONDITIONER BY PLUG-IN JUMPERS. THE READING CAN NOT BE MODIFIED IN ENGINEERING UNITS, UNLESS THE AMPLIFIER IS MODIFIED. THEREFORE USING THE STANDARD AMPLIFIER THE DISPLAY WILL SHOW THE VALUES INDICATED ON THE TABLE. THE INPUT ALLOWS DIRECT CONNECTION TO A CURRENT TRANSFORMER (CT) WITH A 5 Aac. SECONDARY, WITHOUT NEED FOR AN INTERMEDIATE STEP DOWN.
