Brief Information about Measurement Categories
Measurement Category IV is applicable to test and measuring circuits connected at the source of the building’s low-voltage MAINS installation. Examples are measurements on devices installed before the main fuse or circuit breaker in the building installation. Measurement Category III is applicable to test and measuring circuits connected to the distribution part of the building’s low- voltage MAINS installation. Examples are measurements on distribution boards (including secondary meters), circuit breakers, wiring, including cables, bus bars, junction boxes, switches, socket outlets in the fixed installation, and equipment for industrial use and some other equipment such as stationary motors with permanent connection to the fixed installation.
Measurement Category II is applicable to test and measuring circuits connected directly to utilization points (socket outlets and similar points) of the low- voltage MAINS installation. Examples are measurements on MAINS CIRCUITS of household appliances, portable tools and similar equipment.

Analog bar-graph
The analog bar graph provides a visual indication of measurement like a traditional analog meter needle. It is excellent in detecting faulty contacts, identifying potentiometer clicks, and indicating signal spikes during adjustments.

Average sensing RMS calibrated

RMS (Root-Mean-Square) is the term used to describe the effective or equivalent DC value of an AC signal. Most digital multimeters use average sensing RMS calibrated technique to measure RMS values of AC signals. This technique is to obtain the average value by rectifying and filtering the AC signal. The average value is then scaled upward (calibrated) to read the RMS value of a sine wave. In measuring pure sinusoidal waveform, this technique is fast, accurate and cost effective. In measuring non-sinusoidal waveforms, however, significant errors can be introduced because of different scaling factors relating average to RMS values.

True RMS
True RMS is a term which identifies a DMM that responds accurately to the effective RMS value regardless of the waveforms such as: square, sawtooth, triangle, pulse trains, spikes, as well as distorted waveforms with the presence of harmonics. Harmonics may cause :

1. Overheated transformers, generators and motors to burn out faster than normal
2. Circuit breakers to trip prematurely
3. Fuses to blow
4. Neutrals to overheat due to the triplen harmonics present on the neutral
5. Bus bars and electrical panels to vibrate

Crest Factor
Crest Factor is the ratio of the Crest (instantaneous peak) value to the True RMS value, and is commonly used to define the dynamic range of a True RMS DMM. A pure sinusoidal waveform has a Crest Factor of 1.4. A badly distorted sinusoidal waveform normally has a much higher Crest Factor.

OPERATION

NOTE

Before and after hazardous voltage measurements, test the voltage function on a known source such as line voltage to determine proper meter functioning.

AutoCheckTM mode (Models 525s, 521s, 829s only)
This innovative AutoCheckTM feature automatically selects measurement function of DCV, ACV or Resistance ( ) based on the input via the test leads.

• With no input, the meter displays “Auto” when it is ready.
• With no voltage signal but a resistance below 60M is present, the meter displays the resistance value. When below “Audible Threshold“ is present, the meter further gives a continuity beep tone.
• When a signal above the threshold of 1.5V DC or 3V AC up to the rated 1000V is present, the meter displays the voltage value in appropriate DC or AC, whichever larger in peak magnitude.

Note:
*Range-Lock and Function-Lock Feature: When a measurement reading is being displayed in AutoCheckTM mode, press the RANGE or SELECT button momentarily 1 time can lock the range or function it was in. Press the button momentarily repeatedly to step through the ranges or functions.

• As Hazardous-Alert: When making resistance measurements in AutoCheckTM mode, an unexpected display of voltage readings alerts you that the object under test is being energized.
• Ghost-voltage Buster: Ghost-voltages are unwanted stray signals coupled from adjacent hard signals, which confuse common multimeter voltage measurements. Our AutoCheckTM mode provides low (ramp-up) input impedance (approx. 3kΩ at low voltage) to drain ghost voltages leaving mainly hard signal values on meter readings. It is an invaluable feature for precise indication of hard signals, such as distinguishing between hot and open wires (to ground) in electrical installation applications.

NOTE:
AutoCheckTM mode input impedance increases abruptly from initial 3kΩ to a few hundred kΩ’s on high voltage hard signals. “LoZ” displays on the LCD to remind the users of being in such low impedance mode. Peak initial load current, while probing 1000VAC for example, can be up to 471mA (1000V x 1.414 / 3kΩ), decreasing abruptly to approx. 3.1mA (1000V x 1.414 / 460kΩ) within a fraction of a second. Do not use AutoCheckTM mode on circuits that could be damaged by such low input impedance. Instead, use rotary selector or high input impedance voltage modes to minimize loading for such circuits.

MAINTENANCE

NOTE

To avoid electrical shock, disconnect the meter from any circuit, remove the test leads from the input jacks and turn OFF the meter before opening the case. Do not operate with open case. Install only the same type of fuse or equivalent

Calibration
Periodic calibration at intervals of one year is recommended to maintain meter accuracy. Accuracy is specified for a period of one year after calibration.
If the self-diagnostic message “rE-O” is being displayed while powering on, the meter is re-organizing internal parameters. Do not switch off the meter, and it will be back to normal measurement shortly. However, if the self- diagnostic message “C_Er” is being displayed while powering on, some meter ranges might be largely out of specifications. To avoid misleading measurements, stop using the meter and send it for re-calibration. Refer to the LIMITED WARRANTY section for obtaining warranty or repairing service.

Cleaning and Storage
Periodically wipe the case with a damp cloth and mild detergent; do not use abrasives or solvents. If the meter is not to be used for periods of longer than 60 days, remove the battery and store it separately

Trouble Shooting

If the instrument fails to operate, check battery, fuses, leads, etc., and replace as necessary. Double check operating procedure as described in this user’s manual
If the instrument voltage-resistance input terminal has subjected to high voltage transient (caused by lightning or switching surge to the system) by accident or abnormal conditions of operation, the series fusible resistors will be blown off (become high impedance) like fuses to protect the user and the instrument. Most measuring functions through this terminal will then be open circuit. The series fusible resistors and the spark gaps should then be replaced by qualified technician. Refer to the LIMITED WARRANTY section for obtaining warranty or repairing service.
