USING RANGE EXTENSION ACCESSORIES

HEAVY CURRENT MEASUREMENT

(a) Currents between 10 A and 1000 A d.c. may
be measured by use of an appropriate shunt
accessory.
(b) Current Clamp DCM2031
Currents to 400 A a.c. may be measured using
the multimeter current clamp DCM2031.
Full instructions for their use are supplied
with the current clamps.

TEMPERATURE MEASUREMENT

The Model 8mk7 may be adapted to measure
temperature by using one of a range of
multimeter temperature probes available.
The right hand switch on the instrument is set to
the "DC . . ." position and the left hand switch to
the appropriate range for the probe being used.
Many probes have a sensitivity of 1 mV/°C.
Therefore, set it to the 100 mV (50 µA) or 3 V
position (on this latter range deflection will be
limited by the max. temperature of the probe).
Connect the probe leads to the red and black
instrument terminals matching the colours to give
the correct polarity. For negative temperatures the
'Rev MC' button may be used to give an 'on
scale' reading.
To obtain a temperature measurement, apply the
probe tip to the item under test and press the
push-button on the probe handle.
