WARNING AND PRECAUTIONS
To avoid possible electric shock or personal injury, and to avoid possible damage to the meter or to the equipment under test, comply with the following practices: Do not use the meter if it is damaged. Before you
use the meter, inspect the case. Pay particular attention to the insulation surrounding the connectors.
Inspect the test leads for damaged insulation or

Do not use the meter if it operates abnormally.
Protection may be impaired. When in doubt, have the meter serviced.
Do not operate the meter around explosive gas,
vapor, or dust.
Do not apply more than the rated voltage, as
marked on the meter between terminals or between any terminal and earth ground.
Before use, verify the meter's operation by
measuring a known voltage.
When measuring current, turn off circuit power
before connecting the meter in the circuit.
When servicing the meter, use only specified
replacement parts. Do not use the Meter in a manner not specified by this manual or the safety features of the meter may be impaired.
Use with caution when working above 30V ac rms,
42V ac peak, or 60V dc. Such voltages pose a shock hazard.
When using the probes, keep your fingers behind
the finger guards on the probes.
Connect the common test lead before you
connect the live test lead. When you disconnect test leads, disconnect the live test lead first.
Remove the test leads from the meter before you
open the battery door. Do not operate the meter

MAINTENANCE
Beyond replacing batteries and fuses, do not attempt to repair or service your Meter unless you are qualified to do so and have the relevant calibration, performance test and service instruments. The recommended calibration cycle is 12 months.
To clean the terminals
a) Push the Meter OFF and remove test leads. b) Shake out any dirt that may be in the terminals. c) Soak a new swab with isopropyl and work around
the inside of each input terminal
d) Use a new swab to apply a light coat of fine
machine oil to the inside of each terminal.
FUSES TEST
Warning To avoid electric shock or injury, remove the test leads and any input signals before replacing the fuses
1. Turn the rotary switch to 200mA position.
2. Use a multimeter to measure resistance of
"VmA" terminal or 10A terminal to COM terminal.
A good mA terminal or 10A terminal fuse is
indicated by a reading between 0 and 10Ω.
If the display is overloaded, replace the fuse and
test again.
If the display shows any other value, have the meter

serviced. See "Service and Parts" later in this manual.
BATTERY AND FUSE REPLACEMENT
1) Battery and fuse replacement should only be
done after the test leads have been disconnected and power is off.
2) Loosen screws with suitable screwdriver and
remove case bottom.
3) The meter is powered by 1.5V battery (AAAx2).
Snap the battery connector leads to the terminals of a new battery and reinsert the battery into the case top. Dress the battery leads so that they will not be pinched between the case bottom and case top.
4) The meter is protected by fast action fuse
0.2mA/250V, dimensions is ¢5*20mm.
5) Replace the case bottom and reinstall the three
screws, never operate the meter unless the case bottom is fully dosed.

八、 測量操作說明 1.直流電壓及交流電壓測量 a)將紅錶棒插入“VΩmA",黑錶棒插入“COM"
插孔。 b)將功能量程開關置於直流電壓檔位,並將錶棒並
聯到待測電源或負載上。
c)從液晶顯示幕讀取測量結果。
注意:不要測量高於 500V 的電壓,雖然有可能讀 得讀數,但也可能會損壞內部電路及傷害到您。在測 量之前如不知被測量電壓值的範圍時,應將最程開關 置於最高量程檔,根據讀數需要逐步調低測量量程。 當液晶顯示幕只在高位顯示“1"時,說明已超量程, 須調高最程。在每一個量程檔,儀錶的輸入阻抗均為 10MΩ,這種負載效應在測量高阻電路時會引起測量 誤差,如果被測電路阻抗10KΩ,誤差可以忽略(0.1% 或更低)。
2.直流電流測量 a)將紅錶棒插入“VΩmA"或 l0A 插孔,黑錶棒插
入“COM"插孔。
b)將功能量程開關置於直流電流檔位,並將錶棒串
聯到待測電源或電路中。
c)從顯示器上讀取測量結果。
注意:如果不知被測電流值的範圍時,應將量程開 關置於高量程檔,根據讀數需要,逐步調低。在 mA 輸入插孔,輸入超載會將內置保險絲熔斷,須及時予 以更換,保險絲尺寸為:Φ5×20mm,電氣規格 F200mA /250V; 10A 輸入插孔,內部沒有設置保險絲,為了安 全使用,每次測最時間應≤10 秒,間隔時間≥15 分鐘。
19
3.電阻測量
a)將紅錶棒插入“VΩmA"插孔,黑錶棒捅入
“COM"插孔。
b)將功能量程開關置於電阻測量檔位,並將錶棒並
聯到待測電阻上。
c)從顯示器上讀取測量結果。
注意:檢測線上電阻時,為了避免儀錶受損,須確 認被測電路已關掉電源,同時電容已放完電,方能進 行測量。在 200Ω檔測量時,測試錶棒引線會帶來 0.5Ω 左右的測量誤差,為了獲得更精確的讀數,可以將讀 數減去紅、黑兩支表和短路的讀數值,作為最終讀數 值。 4.二極體和通斷測量
a)將紅錶棒插入“VΩmA"插孔,黑錶棒插入
“COM"插孔.
b)將功能量程開關置於二極體測量檔位元,井將紅
錶棒連接到被測二極體的正極,黑錶棒連接到被
測二極體的負極。 c)從顯示器上讀取測量結果。 d)將錶棒連接到待測線路的兩端,如果兩端之間電
阻值低於約 50Ω 時,內置蜂鳴器發聲。
注意:為了避免儀錶損壞,線上測試二極體彰,應 先確認電路已被切斷電源,電容已放完電。用二極體 檔可以測量二極體及其它半導體器件 PN 結的電壓 降,對—個結構正常的矽半導體,正向壓降的讀數應
20
該是 0.6V 左右;反向顯“1"即為開路,此時黑錶棒 對應的極為“+",紅錶棒對應的極為“-"。 5.溫度測量(僅 MT-1233C)
a)將溫度探頭的輸出端(正、負極)分別插入
“VΩmA"與“COM"插孔。
b)將功能量程開關置於溫度測量檔位,並將溫度探
頭的測溫端置於待測物面上或內部。
c)從顯示器上讀取測量結果。
注意:隨機所附溫度探頭為 K 型熱電偶,此類熱電 偶的極限溫度為 250℃。如果要測量更高的溫度,, 須另選購其他型號的溫度探頭。無溫度探頭插入儀錶 時,液晶屏顯示的值為儀錶內部溫度值。不要輸入高 於直流 60V 或交流 30V 的電壓,避免損壞儀錶及傷害 到您。 6.方波試驗信號輸出(僅 MT-1233D)
將功能量程開關置於方波檔,則儀錶從“VΩmA" 與“COM"端之間輸出方波信號。
注意:方波試驗信號其諧波較為豐富,可作為建議 信號源修理音響設備等。頻率約為 50Hz,在接 1MΩ 負載情況下,輸出幅度大於 3V。為了避免儀錶損壞, 嚴禁輸出端(紅錶棒)接觸 10V 以上的電壓。
