V. Comprehensive Code
1. Maximum misoperation protection voltage between the input terminal and grounding is 600V.
2. .Maximum over-load protection current of the clamp head terminal is 200A.
3. Maximum indication: 2,000 Counts, 2-3 times of updating per second. Over-range indicates “OL”.Diode: around
3.2V Measuring range: automatic Polarity: automatic
Working temperature: 0’C – 40′( Relative humidity: 0’C -30′(: ,;; 75%, 30′( – 40′(: ,;; 50% Storage temperature: -
10′( – 50′(
4. .Electromagnetic compatibility: In radio-frequency field of 1V/m: total accuracy=dedicated accuracy+5%; as for
radio-frequency field over 1V/m, there is no dedicated index.
5. Working altitude: 0-2,000m
6. Built-in battery: AAA 1.5Vx2 pieces
7. Low battery: LCD displays” a “symbol.
VI. Drawing for Product Panel (Figure 1)
1. Clamp head.
2. Protective shield.
3. Clamp head trigger: press the trigger to open the clamp head.
4. NCV indicator light: if induced AC electric field intensity and induced distance meet the indicated values, alarm
will be given out and indicator light will flash.
5. Function selection knob switch: turning this knob switch to switch to relevant functions on the panel.
6. HOLD/ key: used to lock the measured readings; hold the key for 2 seconds to turn on or off the backlight.
7. ZERO key: used for DCA reset and measurement of voltage /current/resistance/capacitance relative value.
8. SELECT key: used for function selection at compound tap positions, such as ACV/Hz/DCV, resistance/circuit
on-off/ diode/capacitance, ‘C/’F, etc.
9. .LCD display screen: displaying interface of measurement function, symbol, value and so on. 1 a.Positive end
jack: when testing voltage and resistance/ circuit on-off/capacitance/diode and measuring temperature with
probe, insert red probe/temperature probe into this jack.
10. COM end jack: when testing voltage, and resistance/circuit on-off/capacitance/diode and measuring
temperature with probe, insert black probe/temperature probe into this jack.
11. .Clamp head geometric center indication mark.
