Functional Description
46 50,000-count Benchtop Multimeter
Functional Description (continued)
MATH " MATH " mode enables users to measure a given physical magnitude such as:
• Volts (0 - 10 V process, for example)
• Amps (4 - 20 mA current loop, for example)
• Frequency (measuring rate or rotation speed, for example)
• Ohms (resistive position sensor, for example)
convert it and assign the adequate unit in order to obtain a direct reading of
the original magnitude on the instrument.

Keep the " MATH " key pressed down to access and exit this mode.
Six-phase programming is performed by successively pressing " MATH ",
then setting and validating the following via code wheel:
• Definition of measured magnitude
• Choice of measurement range
• Definition of coefficient A of function y = Ax + b
• Definition of coefficient B of function y = Ax + b (SI unit)
• Choice of physical unit prefix to be displayed
• Choice of physical unit to be displayed
MENU The " MENU " mode enables users to define their own preferences for
certain instrument operation options and update internal clock date and
time.

Programming is performed in successive phases by pressing " MENU ",
then setting and validating the following via code wheel:
• Validation or not of beep when pressing a key or during a warning while
unit is in operation.
• Validation or not of automatic stop after 30 minutes operation if, during this
period, no action was performed on the front.
• Step setting of LCD contrast (0, 33, 67, 100 %)
• Parameterisation of transmission speed: 9600 / 19200 / 38400 / 57600.
Other transmission characteristics are fixed (8 data bits, 1stop bit, no
parity).
• When turning instrument on," bASIC " will allow you to find the
instrument’s basic configuration, while " uSER " will show the last "
advanced " configuration set up by the user for each instrument mode;
this particularly allows you to adapt to " multi-user " instrument operation
(choose "bASIC" option).
• 50 Hz or 60 Hz: choice of network frequency used for optimal rejection.
• Parameterisation of plate sensor type, 100 Ω ou 1000 Ω a 0°C, used to
measure temperature.
• Select "FILt On" in order to measure the average value of alternating
signals via VDC mode.
• Allows you to choose 500 mV range input impedance.
