“SAFETY ADVICE

Depending on the internal impedance of the voltage detector there will be a different capability of indicating the presence or absence of operating voltage in case of the presence of interference voltage.

A voltage detector of relatively low internal impedance, compared to the reference value of 100 kΩ, will not indicate all interference voltage s having an original voltage value above the ELV level. When in contact with the parts to be tested, the voltage detector may discharge temporarily the interference voltage to a level below the ELV, but it will be back to the original value when the voltage detector is removed.

When the indication “voltage present” does not appear, it is highly recommended installing earthing equipment before work.

A voltage detector of relatively high internal impedance, compared to the reference value of 100 kΩ, may not permit to clearly indicate the absence of operating voltage in case of the presence of interference voltage.

When the indication “voltage present” appears on a part that is expected to be disconnected of the installation, it is highly recommended confirming by another means (e.g. use of an adequate voltage detector, visual check of the disconnecting point of the electric circuit, etc.) that there is no operating voltage on the part to be tested and to conclude that the voltage indicated by the voltage detector is an interference voltage.

A voltage detector declaring two values of internal impedance has passed a performance test of managing interference voltages and is (within technical limits) able to distinguish operating voltage from interference voltage and has a means to directly or indirectly indicate which type of voltage is present.”

WARNING

• Battery-operated functions and features work only with appropriate internal battery supply, and will not turn on when there is no battery power. Briefly, they are: LCD indication, RCD Leakage-Path, RST Phase Rotation Detection, Electric Field EF-Detection, AC-Detection Shaker, Audible Continuity, Resistance, Capacitance, Backlight & Flashlight etc.
• Accurate indication is assured only when use within the specified operating temperature range.
• Before using the audible beep sound of Continuity, EF-Detection & RCD etc. at locations with a high background noise level, it shall be determined whether the audible signal is perceptible. The audible beep sound is for information only; do not rely on it, especially in high background noise.
• The functioning of the tester shall be checked shortly before and after a test. If indication of one or more steps fails, or if no functioning is indicated, the tester shall no longer be used.

ACV (v) and DCV (v) Operating Voltage Indication
As illustrated, connect test probes to voltage source and observe indication. Do not cover the indicating LEDs (and also the LCDs on TIS 849 & TIS 859) and do not touch the contact electrode during use. The tester turns on automatically at threshold voltages as specified in the specification section.

• LED Successive Indication, Battery-less
  When significant operating ACV is being detected, LEDs (+ LED & – LED) turn on. When significant operating DCV is being detected, + LED turns on for correct test probes polarity, and – LED turns on for reversed polarity. Operating voltage levels are indicated as a series of LEDs in a successive indication manner. These indicating LEDs actually get power from the system under test without the need of an internal battery supply (battery-less).

• LCD Numeric Indication (TIS 849 & TIS 859 only), battery-operated

  • TIS 849 & TIS 859 are further equipped with a battery-operated LCD numeric display for complementary operating voltage indication.
  • WARNING Test the tester on a known functioning circuit or component shortly before and after use to verify tester functioning, or use a proving device, such as the TIS PU1.
  • ELV (Extra Low Voltage) Limit Indication, Battery-less
  • When an operating voltage above the ELV limit (50Vac and/or 120Vdc) is being detected, the ELV-LED turns on. The indicating LED gets power from the system under test without the need of an internal battery supply (battery-less).
  • WARNING This feature is to warn the user of the presence of a voltage above the ELV limit, not for its evaluation.

RCD (Residual Current Devices) Leakage-Path (TIS 849 & TIS 859 only), Battery- operated
As illustrated, connect the tester to the receptacle under test by measuring the voltage across L and PE (live conductor and a protective earth ground). The tester should indicate proper line voltage level.

• RCD Leakage-Path activation is inhibited at <201V or >264V to avoid misuse.
• With proper line voltage level indicating, press momentarily the RCD button to activate. The tester gives flashing RCD-LED accompanied with beep sound as warning during activation. Each activation interval is automatically limited to 5 seconds maximum.
• If the RCD circuit breaker trips (line voltage is cut off), the flashing RCD-LED as well as the voltage indication should turn off.
• If the RCD circuit breaker does not trip (line voltage is still on) within a reasonable short period of time (mostly a fraction of a second), the breaker is either not working properly or there is a wiring problem. WARNING When activated, the tester actually connects to a low impedance load of nominal 6.1kΩ to draw a leakage current of ³30mA typical at 230VAC to trip RCD circuit breakers. In the event of a full continuous 5 second activation interval, the protection PTC will heat up and affect the load current magnitude thereafter. Allow cooling for 120 seconds before the next activation then.

NOTE: This function is not intended to identify the effectiveness (trip current and trip time etc as specified by the breaker manufacturers) of breakers. Effectiveness of RCD circuit breakers should be checked by RCD testing, measuring or monitoring equipment under the scope of IEC61557-1 & IEC61557-6.

RST Phase Rotation Detection
(TIS 849 & TIS 859 only)

Battery-operated
As illustrated, connect test probes to voltage source and observe indication. The tester should indicate proper operating voltage level for good connections. The Black probe (L1) connection is always considered as the Reference-Phase* R.

• If the annunciator turns on, it indicates that a “Right” phase-rotation is being detected. The Red probe (L2) connection is then the 2nd Phase S. The remaining unconnected connection is the 3rd Phase T. Swap the two probe connections to get reversed annunciator , as for proper functioning verification.
• If, however, the annunciator turns on, it indicates that a “Left” phase-rotation is being detected. The Red probe (L2) connection is then the 3rd Phase T. The remaining unconnected connection is the 2nd Phase S. Swap the two probe connections to get reversed annunciator , as for proper functioning verification.

NOTE: This function works only on Y-connection 3P4W systems. It does not work on Δ-connection 3P3W systems that do not have an earth-ground neutral. It, however, can work on High-leg Δ-connection 3P3W systems by using the high- leg as the Reference-Phase R for Black probe (L1) connections. That is, simply test and find out the high-leg which has the highest voltage (Ö3 times to that of the other legs) with respect to earth-ground, and use it as the Reference- Phase R for Black probe (L1) connections. High-leg Δ-connection systems have a centre-tapped neutral connected to earth-ground.

WARNING It is important to swap the tester probe connections to get reversed annunciator indication for proper functioning verification.

AC-Detection Shaker (TIS 849 & TIS 859 only), Battery-operated
The shaker turns on when significant ACV is being detected via the test probes.

Electric Field EF-Detection, Battery-operated
As illustrated, press-and-hold the EF button to enter and remain at EF- Detection feature. The EF-LED turns on. Signal strength is indicated by the flashing rate of Continuity-LED accompanied with beep sound. TIS 849 & TIS 859 further display “EF” when they are ready, and display signal strength as successive bar-graph segments on the LCD.

Non-Contact EF-Detection:
An antenna is located along the top-right side of the tester, which detects electric field surrounds conductors. It is ideal for tracing live wiring connections, locating wiring breakage and to distinguish between live or earth connections.

Probe-Contact EF-Detection:
For more precise indication of live wires, such as distinguishing between live and ground connections, use the Black (-) test probe for direct contact detection.

Audible Continuity Function, Battery-operated
Short the two test probes together for quick power-on and continuity function verification. As illustrated, the Continuity-LED turns on accompanied with a continuous beep sound indicate a complete circuit. During power-on, TIS 849 & TIS 859 LCD further display “ ” for open circuits and “ ” & “ ” for complete circuits. Audible-Continuity is convenient for checking wiring connections and operation of switches.

Backlight & Flashlight (TIS 849 & TIS 859 only), Battery-operated
Press the button momentarily to toggle on/off the backlight & flashlight.

Resistance Function (TIS 859 only), Battery-operated
As illustrated, press-and-hold the Ω button for 1 second to enter the Resistance function directly from power-off. Press Ω button momentarily to toggle between Continuity function during power-on. The resistance value is displayed on the LCD in auto-ranging mode.

Capacitance Function (TIS 859 only), Battery-operated
As illustrated, press-and-hold the button for 1 second to enter the Capacitance function directly from power-off. Press the button momentarily to toggle between Continuity function during power-on. The Capacitance value is displayed on the LCD in auto-ranging mode.

Power On/ Off for Battery-Operated Functions and Features

The battery-operated portion of the tester turns on automatically when the two test probes are shorted together, or significant operating voltage level is detected. See specifications for power-on threshold details. Where available, momentary press the Resistance, Capacitance or Backlight button can also manually turn on the tester. The tester turns off automatically after no further significant testing or push-button activities for approximately 8 seconds for Resistance & Capacitance functions or 16 seconds for others.

MAINTENANCE

WARNING
To avoid electrical shock, disconnect the tester from any circuit and remove the detachable test probe from the input jack before opening the case and/or the battery access door. Do not use the tester with open case and/or the battery access door. Do not attempt to repair this unit. It contains no user-serviceable parts. Unauthorised persons should not disassemble the tester.

Cleaning and Storage
Periodically wipe the case with a damp cloth and mild detergent; do not use abrasives or solvents. The tester should be kept dry and clean. If the tester is not to be used for periods of longer than 60 days, remove the batteries and store them separately

Trouble Shooting

If the tester fails to operate, check batteries, probes, etc., and replace as necessary. Double check operating procedure as described in this user’s manual If the tester voltage-continuity input has subjected to high voltage transient (mostly caused by lightning or switching surge to your system) by accident or abnormal conditions of operation, the series protective impedance could become high impedance like fuses to protect the user and the tester. Most measuring functions through this input will then be open circuit. The protective impedance should then be replaced by qualified technician. Refer to the LIMITED WARRANTY section for obtaining warranty or repairing service.

Low-battery indication

• For TIS 849 & TIS 859, the LCD annunciator turns on to indicate low-battery.
• For TIS 839, EF and Continuity LEDs flashing simultaneously to indicate low battery.

WARNING; Always power-on the tester and check for low-battery status before using battery-operated functions. Replace low-batteries ASAP to maintain tester accuracy and functionality.

Battery replacement
Loosen the 2 screws from the battery access door of the case bottom. Lift the battery access door up. Care should be taken not to displace or lose the sealing joint from around the battery cover. Replace the batteries. Re-fasten the screws.
The tester uses 1.5V AAA Size (NEDA 24A or IEC LR03) alkaline battery X 2.
