SAM Voltage Tester (SVT)
Portable, battery-operated tester
SAM Voltage Tester is a portable, battery-operated tester designed to measure the clamping voltage and DC breakdown voltage of most surge protective devices. It is specifically designed to test the Elsafe range of SAM cassettes, and also has the capability to test other devices. It is suitable for testing gas tubes, carbon gaps, MOVs, Zener and avalanche diodes and thyristor devices, both as components and as complete protectors.

Suitable for following termination modules for simple connection to Elsafe products:
- 216600A – FOR MOST SAM CASSETTES
- 216605A – FOR VZC SAM CASSETTES
- 557022 – FOR EQUALISING ARRESTOR MODULE
- 108816 – FOR SSI MKII MODULES 108815 (This base is no longer sold)
- Plugs and flexible leads for testing other devices.
A test matrix is supplied which lists the range of acceptable clamping voltages for each Elsafe product. The clamping voltages of the internal surge protecting components change after each surge, indicating internal damage.
For optimal performance and reliable surge protection it is strongly recommended that the SAM cassette be replaced if the measured clamping value is outside of the specified tolerances shown in the test matrix.
Testing Procedure:
1. Find the SAM Module that needs to be tested in the Test Matrix.
2. Select the correct test according to the Test Matrix via the TEST SELECTOR.
3. Press and hold TEST button until a stable (or slowly rising) voltage reading shows. Check the voltage shown is within
the range shown on the Test Matrix, if it is not replace the SAM module.
4. If more than one test is required by the Test Matrix then proceed to the next test and return to step 2.
5. Complete all recommended tests according to the test matrix.
6. Switch Selector to OFF position. Push DISCHARGE button and remove test SAM.
For all other devices select TEST 6 (External Banana Connections)
1. Connect the test leads to the banana connections, the other end to the Unit Under Test.
2. Press and hold the TEST button until a stable voltage reading is shown.
3. Switch Selector to OFF position. Push DISCHARGE button, disconnect test leads from Unit Under Test.
WARNING! When using the external connectors it is possible to be exposed to a hazardous voltage and there is a risk of electric shock.
Charging Procedure
If the LOW BATTERY LED lights up when testing a SAM module this indicated that the internal battery needs to be charged.[/caption]
Plug the supplied charger into the Mains Supply and the other side into the Sam Voltage Tester CHARGE port.
The LED on the Charger should turn RED.
Charging is complete when the LED on the Charger turns GREEN
When testing the high voltage clamping cassettes the battery will need to be fully charged.
