UEi Test Instruments DM200 - DISCONTINUED - Manual (Page 3)

WARNING!
To avoid electric shock, be sure to turn off the meter’s power and
disconnect both test leads from any equipment before you remove
or install batteries.
WARNING!
Under NO circumstance should you expose batteries to extreme heat or
fire as they may explode and cause injury.
NOTE: If you do not plan to use the meter for a month or more,
remove the battery and store it in an area that won’t be damaged by a
leaking battery.

Electrical Specifications
Accuracy is given as +/- (% of reading + number of least significant
digits) at 65˚ to 80˚F with relative humidity up to 80%, valid for a period
of one year after calibration. AC conversions of this meter are average
responding and calibrated to the RMS value of a sine wave input.

Continuity Testing
1. Connect the black test lead to the terminal marked “COM” and
the red test lead to the terminal marked “V Ω“.
2. Set the rotary switch to the continuity/resistance function, and
note the overload symbol on the display.
3. For continuity testing, touch the red lead to one side of the circuit
(i.e. wire) and the black lead to the other side. Ensure your circuit
is isolated from other circuit paths to prevent testing the wrong
path. If the circuit resistance is approximately 50Ω or less a
continuous tone will sound.

Periodic service
WARNING!
Repair and service of this instrument is to be performed by qualified
personnel only. Improper repair or service could result in physical
degradation of the meter. This could alter the protection from
electrical shock and personal injury this meter provides to the
operator. Perform only those maintenance tasks that you are
qualified to do.
These guidelines will help you attain long and reliable service from
your meter:
1. Calibrate your meter annually to ensure it meets original
performance specifications.
2. Keep your meter dry. If it gets wet, wipe it dry immediately. Liquids
damage electronic circuits.
3. Whenever pra c t i cal, keep the meter away from dust and dirt, which
can cause premature wear.
4. Although your meter is built to withstand the rigors of daily use, it
can be damaged by severe impacts. Use reasonable caution when
using and storing the meter.
Cleaning and Decontamination
Periodically clean your meter’s case using a damp cloth. DO NOT use
abrasives, cleaning solvents or strong detergents, as they may damage
the finish or affect the reliability of the structural components.
Battery Replacement
When the “ “ symbol appears on the left side of the display, the
battery must be replaced immediately. Low battery voltage can cause
incorrect readings and consequential damage. To replace the battery
remove the meter from the boot. To do this remove the meter leads,
pull the top of the boot away from the meter and slide the meter out of
the boot. Remove the two screws securing the battery access cover
using a number one Phillips screw driver. Replace the battery with the
specified 9V Alkaline battery.
NOTE: There are no replacement fuses. (This meter has thermistor
protection)
