Portable Surge Protective Device Tester
WTH-CS/BT-1000V portable handheld LCD display Break-over Voltage Leakage current tester for surge protective device
applies to the measurement of the parameters of the voltage-limiting type and switch-type SPDs. These data are used for
evaluating the operating characteristics of the SPDs and the product selection to cooperate with the construction site.
Model & Ordering Code
Model: WTH-CS/BT-1000V
Ordering Code: US128002
UPC/EAN Code: (0) 811914030058
Main Features of WTH-CS/BT-1000V SPD Tester:
1. Portable and convenient use with batteries, rechargeable
batteries or external power supply; suitable for office and onsite
measurements
2. Easy, rapid and precise measurement by pressing one button
for testing and immediate display SPD data features
3. While MOV testing, a buzzer will sound if the deviation of
break-over voltage exceeds the default value by ± 5%.
4. While MOV testing, a buzzer will sound if the leakage current
exceeds 20 μA.
5. Applied to testing both MOV-type and GDT- type SPDs
6. Precise break-over voltage test under the constant current
1mA
7. Precise leakage current test under 75% of the break-over
voltage
8. The voltage of the tester can be boosted up to 1000V DC
9.Convenient multimeter calibration methods
Conformity of Test Result
The breakover voltage of surge protective device refers to the value of the voltage which is tested when 1mA current flows
through the surge protective device while the testing voltage is boosted.
Since only the value of Uc is marked on the label of a surge protection product, the breakover voltages of the products
specified in corresponding with the Uc values by different manufacturers during actual production maybe vary. The
following are the parameters of "Watchful Eye" surge protective devices for reference.
