070 Series ANSI Switchboard Meters This high quality range of Switchboard instruments complies with the American specification ANSI-C39.1 (1981) accuracy class 1. Available in 41/2" and 83/4" case sizes, their rugged design characteristics suit the most demanding of environmental applications. This extensive range of analogue and digital/analogue meters utilise a high shock oil dampened movement, and provide 1% accuracy for all RMS AC and DC ranges. The range offers various customised options and features. Description JIS dimensioned product available on request 070 series offers two case sizes, 41/2" (Models 075, 077 & 078) and 83/4" (Model 079). Model 078 is high shock hermetically sealed and all models have heavy gauge pressed steel cases. Mounting is by four integral studs. Models 075 & 077 are a one piece flame retardant polycarbonate moulding with a matt black finished bezel area, and a specially contoured window to minimise reflection from adjacent light sources. Model 079 has a black pressed steel bezel with a toughened glass window, and Model 078 has a die-cast bezel and a projecting moulded toughened glass window, which incorporates a gas tight zero adjuster. Scales are 240 moving iron and 250 moving coil with parallax error-free platform dials. Standard dials are matt white with black printed scales and bar knife-edge pointers. Black dials with white or yellow scales and pointers are also available. General options include supplementary red pointer (075 & 077), slave pointer, calibration for non standard ambient temperatures, special scales, trim potentiometers, and Illuminated dials with white or red light sources.

Wattmeters & Varmeters The Crompton 70 series of A.C. Wattmeters and Varmeters incorporate a DC moving coil taut band indicator with the Crompton designed micro-circuit Watt transducer PCB to read power on single phase or three phase systems. Varmeters can be supplied with internal phase shifter or with external phase shifter if preferred. In the interest of standardisation, preferred Wattmeter scale marking for common current and voltage transformers are listed on the following pages. Instruments may be supplied with zero left or center zero scales at the same list price. Scaling Since Wattmeter and Varmeter current circuits are frequently connected in series, they should have equal current carrying capacity. This means that to assure equality the sum of the left and right end-scale values of the Varmeters should be equal to or greater than the full scale value of the Wattmeter (or the higher of the end-scale values if center or offset zero). Instruments 10,000 kilowatts and over are marked in megawatts. Center zero or offset zero Watt and Varmeters are marked "IN" for left deflection and "OUT" for right deflection. Preferred scales may be calculated for Wattmeters and varmeters not listed on the charts. Scale Watts must be one of the standard full scale dial markings shown on the charts. Calibration For full load value of Watts or Vars, assuming unity power factor: 1ph 2 wire Watts = amps x volts 3ph 3 wire Watts = amps x line to line volts x 3 3ph 4 wire Watts = amps x line to neutral volts x 3 Minimum scale values are obtained by multiplying resultant Watts using above formula x 0.7 and selecting next highest standard scale. For maximum scale value multiply x 1.3 and select next lowest standard. If scale calculates to an exact listed value use it rather than the next higher or lower value. Note: When ordering Wattmeters and Varmeters specify C.T. ratio, V.T. ratio and required scale.
