Model 2000 Digital Multimeter Quick Start Guide
Section 1: Introduction
Math
To enable and configure a math operation, press SHIFT and then the desired math key (MX+B, %,
dBm or dB). Use the
,
,
▲
and
▼
keys to configure the math operation and press ENTER
when done. Pressing SHIFT and then the related math key a second time disables the math
operation.
MX+B
Y = mX + b
Where: X is the normal display reading.
m and b are the user entered constants.
Y is the displayed result.
Percent (%)
Where: Input is the normal display reading.
Reference is the user entered constant.
Percent is the displayed result.
dBm
Where: V
IN
is the DC or AC input signal.
Z
REF
is the specified reference impedance.
dB
Where:V
IN
is the DC or AC input signal.
V
REF
is the specified voltage reference impedance.
Measuring continuity
With this feature, the instrument alerts you with a beep when a resistance reading is below the set
level. To measure continuity, press SHIFT and then CONT. Use the
,
,
▲
and
▼
keys to set the
resistance threshold level, and press ENTER. Connect the test leads to INPUT HI and LO.
Testing diodes
With this feature, the instrument measures the forward voltage drop of general-purpose diodes
and the zener voltage of zener diodes. To test diodes, press SHIFT and then (
). Use the
▲
and
▼
keys to select the test current.
Limit operations
With this feature, you can check to see of readings are within (“IN” displayed), below (“LO”
displayed) or above (“HI” displayed) specified low and high reading limits. You can also set the
instrument to beep when readings are inside or outside of the limit range.
