KIKUSUI Ground Bond Tester TOS6210 | Nihon Denkei Co.,Ltd. Singapore Branch

Ground Bond tester supporting standard compliance tests up to 60A

While inheriting the basic performance and functions of its predecessor (TOS6200), such as a constant current driving system that provides current waveforms with little skew and high measurement accuracy, the TOS6210 tester extends the maximum test current from 30 A to 60 A, which is demanded by the new standard. In addition, the tester also lets you judge the acceptability of the device under test based on the drop in voltage, as required in the standard.

What’s more, you can preset test conditions of up to 20 different types of safety standards, such as those for information technology equip- ment, home appliances, medical devices, and measuring in- struments, in the memory on the main unit’s panel. A simple memory call operation allows you to set up a pro- tective earth or protective bonding continuity test as stipu- lated in UL and other relevant specifications including IEC and JIS standards. The tester also features a set of functions that meet the specific needs of testing personnel, such as an offset cancellation function and a memo function that allows you to input calibration dates, production numbers, and other test-related information and read the input information later via the GPIB or RS232C interface.

Pass/fail judgement function *3

Resistance value-based judgement		Window comparator system If a resistance value equal to or greater than the upper reference value is detected, a FAIL determination is returned. If a resistance value equal to or less than the lower reference value is detected, a FAIL determination is returned. If a resistance value has been judged as FAIL, the tester shuts off the output and generates a FAIL signal. If the set time elapses without abnormalities, the tester shuts off the output and generates a PASS signal.
	Setting range for the upper reference value (UPPER)	0.001 to 0.600 Ω
	Setting range for the lower reference value (LOWER)	0.001 to 0.600 Ω
	Resolution	0.001Ω
	Judgment accuracy	± (2% of UPPER + 0.003 Ω)
Sampled voltage value-based judgment		Window comparator system If a voltage value equal to or greater than the upper reference value is detected, a FAIL determination is returned. If a voltage value equal to or less than the lower reference value is detected, a FAIL determination is returned. If a resistance value has been judged as FAIL, the tester shuts off the output and generates a FAIL signal. If the set time elapses without abnormalities, the tester shuts off the output and generates a PASS signal.
	Setting range for the upper reference value (UPPER) *4	0.01 to 5.40 V
	Setting range for the lower reference value (LOWER)	0.01 to 5.40 V
	Resolution	0.01V
	Judgment accuracy	± (2% of setting + 0.05 V)
Calibration		Calibration is performed with the rms value of the sine wave, using a pure resistance load.
LED	PASS	Lights for approximately 0.2 sec when the measured value has been judged as PASS. It is lit continuously when the PASS holding time is set to HOLD.
	UPPER FAIL	Lights if a resistance or voltage value equal to or greater than the upper reference value is detected and judged FAIL.
	LOWER FAIL	Lights if a resistance or voltage value equal to or greater than the upper reference value is detected and judged FAIL.
Buzzer		The buzzer sounds for the pass holding time has been set if the measured value has been judged as PASS. The buzzer sounds continuously under the following condition: The measured value has been judged as PASS when the PASS holding time is set to HOLD. The measured value has been judged as UPPER FAIL. The measured value has been judged as LOWER FAIL. The buzzer volume for FAIL or PASS judgment are adjustable. Note that it cannot be adjusted individually since setting is shared with the setting for PASS.

*1 Time limitation with respect to output. The heat radiation capacity at the output block of the tester is designed to be one-third of the rated output, accounting for size, weight, cost, and other factors. Always use the tester within the limitation values given below. Use of the tester beyond these limits will cause the temperature of the output block to rise excessively, potentially tripping the internal protection circuit. In this case, suspend testing for approximately 30 minutes, then press the STOP switch. When temperatures fall to normal levels, the tester will revert to ready status.

Ambient temperature t (°C)	Test current I (A)	Pause time	Maximum allowable continuous test time
t ≤ 40°	40 < I ≤ 60	Equal to or greater than the test time	≤ 10 minutes
	20 < I ≤ 40	Equal to or greater than the test time	≤ 30 minutes
	I ≤ 20	Not required	Continuous output possible

*2 About ohmmeter’s response time. A resistance value is instantaneously obtained, calculated using the measured voltage and current values. The response time of the ohmmeter complies with the response times of the voltmeter and ammeter.
*3 Resistance value-based and sampled voltage value-based judgments cannot be simultaneously conducted.
*4 Limited by the maximum rated output and the output terminal voltage. The tester can be used within the range shown below.
*5 Not applicable to custom order models.
*6 Only on models that have CE marking on the panel.
