 CAUTION : To avoid damage to the meter, do not expose it to sprays, liquids, or solvents. Clean the exterior of the meter by removing dust with a lint-free cloth. Use care to avoid scratching the clear plastic display filter. For further cleaning, use a soft cloth or paper towel dampened with water. You can use a 75% isopropyl alcohol solution for more efficient cleaning.  CAUTION : To avoid damage to the surface of the meter, do not

use abrasive or chemical cleaning agents.

9.1 BATTERY INSTALLATION OR REPLACEMENT The meter is powered by 9V power regulated from transformer or 6 pieces of 1.5V battery. Refer to Figure 4 and use the following procedure to replace the battery. 1. Disconnect test leads from any circuit under test, turn the ON/ OFF switch on the rear panel to off and remove the test leads from the meter. 2. Open the accessory compartment by pressing back and up on the

5. Replace the new battery to battery box and snap the battery connector leads to the terminals on battery box. 6. Reinsert the battery cover in the multimeter.

FUSE REPLACEMENT Refer to Figure 5 and use the following procedure to examine or replace the meter fuse. 1. Do steps 1 through 2 of the “ Battery Replacement ” procedure. 2. Using a slot-head screwdriver, key, or other appropriate tool, pry open the top of the fuse cover and lift the cover out. 3. Remove the defective fuse by gently prying one end of the fuse loose and sliding the fuse out of the fuse holder. 4. Install a new fuse of the same size and rating. Make sure the new fuse is centered in the fuse holder. 5. Replace the fuse cover in the meter.

200 серия цифровых мультиметров APPA, так называемого «настольного типа».

Они были разработаны для использования в различных условиях эксплуатации, сочетающих необходимость применения как стационарного вольтметра так и переносного мультиметра. Основной конструктивной особенностью мультиметров является универсальное питание. Оно может осуществляться как от сети 220 В, так от внутренних источников суммарным напряжением 9 В. Конструкция батарейного отсека позволяем использовать любые батареи как 1,5 В так и 9 В. Это позволяет использовать прибор при питании от сети в условия производственного цеха, лаборатории или другого помещения, а при необходимости проведения выездного измерения или проведения измерения на открытом воздухе использовать автономное питание. Конструкция прибора позволяет использовать их как в помещении на столе с встроенной подставкой, так и в полевых условиях на ремне. Внутренний отсек мультиметра позволяет хранить не только измерительные щупы, но и мелкий монтажный инструмент. Функциональные возможности различных мультиметров 200-серии очень широки — от измерения обычных величин токов, напряжения и сопротивлений, до возможностей измерения мощности, температуры, скважности сигнала и обработки результатов измерения величин (выбор минимального или максимального значения, вычисление среднего значения, удержание результата измерения, фиксация пикового значения и др.) входных сигналов и подключения к персональному компьютеру. Между собой мультиметры отличаются функциональными возможностями и погрешностью измерения.

9. MAINTENANCE Protect the meter from adverse weather
conditions. The meter is not

waterproof. Do not expose the LCD display to direct sunlight for
long

periods of time.

CAUTION : To avoid damage to the meter, do not expose it to
sprays, liquids, or solvents.

Clean the exterior of the meter by removing dust with a
lint-free cloth.

Use care to avoid scratching the clear plastic display
filter.

For further cleaning, use a soft cloth or paper towel dampened
with

water. You can use a 75% isopropyl alcohol solution for more
efficient

cleaning.

CAUTION : To avoid damage to the surface of the meter, do not
use abrasive or chemical cleaning agents.

9.1 BATTERY INSTALLATION OR REPLACEMENT The meter is powered by
9V power regulated from transformer or 6

pieces of 1.5V battery. Refer to Figure 4 and use the
following

procedure to replace the battery.

1. Disconnect test leads from any circuit under test, turn the
ON/ OFF

switch on the rear panel to off and remove the test leads from
the

meter.

2. Open the accessory compartment by pressing back and up on
the

button. Remove any stored accessories.

3. Using a slot-head screwdriver, key, or other appropriate
tool, pry

open the top of the battery cover and lift the cover out.

4. Disconnect the battery connector leads and remove the
battery

from the battery box.

5. Replace the new battery to battery box and snap the battery
con-

nector leads to the terminals on battery box.

6. Reinsert the battery cover in the multimeter.
27

FUSE REPLACEMENT Refer to Figure 5 and use the following
procedure to examine or replace the meter fuse.

1. Do steps 1 through 2 of the Battery Replacement
procedure.

2. Using a slot-head screwdriver, key, or other appropriate
tool, pry open the top of the fuse cover and lift the cover
out.

3. Remove the defective fuse by gently prying one end of the
fuse loose and sliding the fuse out of the fuse holder.

4. Install a new fuse of the same size and rating. Make sure the
new fuse is centered in the fuse holder.

5. Replace the fuse cover in the meter.

FEATURE DESCRIPTIONS 6.1 Auto fuse detection The meter checks the
integrity of the internal fuses for the mA, A measurements. If an
open fuse is detected , FUSE is displayed and beep sounds
continuously. 6.2 Probe input guard The meter beeps continuously
and displays ProbE if a probe is inserted in a current input
connector and a measurement other than current is selected. 6.3
Buzzer A single beep indicates correct operation, two beeps
indicate a warning or error condition. Use the Setup menu to set
the buzzer mode on or off.

9. MAINTENANCE Protect the meter from adverse weather
conditions. The meter is not

waterproof. Do not expose the LCD display to direct sunlight for
long

periods of time.

CAUTION : To avoid damage to the meter, do not expose it to
sprays, liquids, or solvents.

Clean the exterior of the meter by removing dust with a
lint-free cloth.

Use care to avoid scratching the clear plastic display
filter.

For further cleaning, use a soft cloth or paper towel dampened
with

water. You can use a 75% isopropyl alcohol solution for more
efficient

cleaning.

CAUTION : To avoid damage to the surface of the meter, do not
use abrasive or chemical cleaning agents.

9.1 BATTERY INSTALLATION OR REPLACEMENT The meter is powered by
9V power regulated from transformer or 6

pieces of 1.5V battery. Refer to Figure 4 and use the
following

procedure to replace the battery.

1. Disconnect test leads from any circuit under test, turn the
ON/ OFF

switch on the rear panel to off and remove the test leads from
the

meter.

2. Open the accessory compartment by pressing back and up on
the

button. Remove any stored accessories.

3. Using a slot-head screwdriver, key, or other appropriate
tool, pry

open the top of the battery cover and lift the cover out.

4. Disconnect the battery connector leads and remove the
battery

from the battery box.

5. Replace the new battery to battery box and snap the battery
con-

nector leads to the terminals on battery box.

6. Reinsert the battery cover in the multimeter.
27

FUSE REPLACEMENT Refer to Figure 5 and use the following
procedure to examine or replace the meter fuse.

1. Do steps 1 through 2 of the Battery Replacement
procedure.

2. Using a slot-head screwdriver, key, or other appropriate
tool, pry open the top of the fuse cover and lift the cover
out.

3. Remove the defective fuse by gently prying one end of the
fuse loose and sliding the fuse out of the fuse holder.

4. Install a new fuse of the same size and rating. Make sure the
new fuse is centered in the fuse holder.

5. Replace the fuse cover in the meter.
