MECHANICAL DATA:
Panel
mounting meters have panel cutout size of 46mm(H) x
92mm(W) with cabinet size of 48mm(H) x 96mm(W) x
110mm(D).
(Choice of panel cutout of 92mm(H) x 92mm(W) with
cabinet size of 96mm(H) x 96mm(W) X 75mm(D) available
optional, at no extra charge for mains operated DPM’s.)
Panel mounting hardware is supplied with the meters.
Cabinet size for portable meters is 100mm(H) X 200mm
(W) X 100mm(D). Portable meters are supplied with mains
cords and test leads.

DISPLAY:
7 segment,
LED type of 13 mm height. 4 digit for frequency measurements. 3½ digit
for the remaining measurements.
Decimal point, negative polarity and over-range indications are
provided in all meters.
RESOLUTION:
1 in 999 for power factore (cos ø) measuerments.
1 in 9999 for frequency and watt measurements.
1 in ± 1999 for all other measurements.
(High resolution of digital meters make them upto 100 times more
accurate than analog meters).
