Percentage deviation ( %)
This function enables the meter to display the percentage amount by
which the reading differs from a nominal value chosen by the user.
It is invaluable for measuring tolerance or stability.
Min-Max storage
The Min-Max function stores the highest and lowest values of a set
of readings.
This facility has many uses such as checking for power supply glitches
and recording peak temperature excursions.
Power measurement in Watts or VA
In addition to dBs, power can be measured in Watts or VA.
For resistive loads the Watts function calculates V
2
/R for any load
resistance between 1W and 10kW, a particularly useful function for
audio measurements.
The VA function makes use of the dual measurement capability and
displays the product of voltage and current.
Safety | Calibration
Comprehensive safety protection
The meters incorporates extensive protection against damage from
accidental overloads on all ranges including 10 Amps.
They also meet the stringent safety requirements of EN61010-1
2010 and EN61010-2-030 2010 for measurements up to 1kV or
600V (Cat. II).
Kensington Security Slot
A Kensington
®
security slot is incorporated into the
rear panel.
This enables the instrument to be secured using the
widely used Kensington cable system.
Closed case calibration
The meter stores its calibration constants in protected memory and
can be recalibrated without ever opening the case.
Automatic data logging
The 1908 can store up to 500 readings at any required time interval
from 1 reading per second up to 1 reading every 3 hours.
A simple recall sequence allows the readings to be scrolled onto the
display whenever required. Alternatively results can be downloaded
using the remote interfaces.
As a result, tedious time related measurement sequences can be
handled automatically without disrupting your work.
Manual storage of readings is also available eliminating the need for
paper and pencil when making a series of measurements.
Storage can also be triggered from contact closure or from the digital
interfaces.
External Triggering
An external trigger connector is provided on the
rear panel.
This provides for external triggering of
measurement hold or measurement log.
An opto-isolated open collector output
is available for synchronisation with the
measurement update.
