Kit consist of

Coating thickness measurer ZCT 777, 2 batteries, case, steel and aluminium foils, operating manual.

General information

ZCT 777 works either on the magnetic induction principle or on the eddy current principle, depending on the type of probe used. You can select the type of probe via MENU system, or it will be work automatically. The gauges conform to the following industrial standards:

GB/T 4956─1985 GB/T 4957─1985 JB/T 8393─1996 JJG 889─95 JJG 818─93

Functions

Measured Coatings: Non-magnetic coatings(e.g. paint, zinc)on steel; Insulating coatings(e.g. paint, anodizing coatings)on no-ferrous metals Operating with MENU easily Two measuring modes: CONTINUE and SINGLE mode Two working modes: DIRECT and GROUP mode(4 groups). DIRECT mode is intended for quick occasional readings.The statistical analysis program can evaluate 80 readings. Unit values are not saved. In GROUP mode, every group memory can store a maximum of 80 single readings, and 5 Statistic values. Statistic Display: AVG, MAX, MIN, NO., S.DEV One point calibrating and two points calibrating independently for each working mode Zero calibrating easily Memory for 320 readings(80 for each group) Delete single readings and all group readings easily

Application

This compact and handy gauge is designed for non-destructive, fast and precise coating thickness measurement. The

principal applications lie in the eld of corrosion protection. It is ideal for manufacturers and their customers, for ofces

and specialist advisers, for paint shops and electroplaters, for the chemical, automobile, shipbuilding and aircraft industries and for light and heavy engineering. The probe can work on both principles, magnetic induction and on the eddy current principle. One probe only is required for coating measurement both on ferrous and non-ferrous metal substrates.

Probe

The Probe systems are spring-mounted in the probe sleeve. This ensures safe and stable positioning of the probe and constant contact pressure. A V-groove in the sleeve of the probes facilitates reliable readings on small cylindrical parts. The hemispherical tip of the probe is made of hard and durable material. Hold the probe by the spring mounted sleeve and put on measuring object.

Measure modes (menu item 2.1)

Single mode (menu item 2.1.1: In Single mode, readings are accompanied by a bleep. All readings taken in this mode will be automatically entered into the statistics program.

Continuous measurement mode (menu item 2.1.2): It can sometimes be of advantage if the probe does not need be raised between each measurement so that there is a running display of readings. All readings taken in this mode will be automatically entered into the statistics program.

Measurement, storage and data processing in the DIRECT and GROUP modes (menu item 2.2). DIRECT mode (menu item 2.2.1). DIRECT mode is intended for quick occasional readings. The statistical analysis program can evaluate 80 readings. The readings and statistical values can be shown on the LC display. When the memory is full, new readings will replace old readings. Note: in this mode unit values are not saved after the instrument is switched off. GROUP mode (menu item 2.2.2-2.2.5). If you work in this mode the word “GROx” must appear on the display. Measure- ments are saved in the free programmable memory. Every group memory can store a maximum of 80 single readings, and 5 Statistic values. When the memory is full, measuring will make sequentially, but not be stored and statistic values won’t

be changed. You will see indication of full memory “FULL” on the display.

If you want you can delete the group with data and values (menu item 4) and also zero the values of calibration (menu item 5).

Probe (menu item 2.3)

The probe can work in three modes. AUTO (menu item (2.3.1): The probe can automatically select the working mode. When Placed on steel (magnetic substrates), it will work in magnetic induction principle. When placed on no-ferrous metals, it will work in eddy current principle. Fe (menu item 2.3.2): The probe works in magnetic induction principle. No-Fe (menu item (2.3.3): The probe works in eddy current principle.

Unit settings (menu item 2.4)

You can choose necessary unit: 10-3 vv (micron), mm.

In “um” mode, the unit will switch to “mm” automatically when value of reading exceeds 850um.

Backlight (menu item 2.5)

You can select ON/OFF in MENU system. Besides, in measuring mode, Press the blue-bar button once to switch ON/OFF backlight.

LCD Statistic (menu item 2.6)

In Menu system mode, The statistic display can be selected between Average, Maximum, Minimum and Sdev. When return to measurement mode, it will be displayed on the lover right of LCD. At the same time, the statistic number of measuring

readings is displayed on the lower left of LCD. Via “statistic view” item in MENU system, you can look through all statistic

values for current group.

Measurement Using Statistics

The gauge calculates statistics from a maximum of 80 readings. Readings can’t be stored in DIR mode. The following statistical values are calculated: NO.: number of readings in Work Mode AVG: average value Sdev. : standard deviation MAX: maximum reading MIN: minimum reading

These data you can see in the menu Statistic view (menu item 1). Use buttons ▲/▼ to navigate through these data.

The sum of readings divided by the number of readings.

average value = ∑x/n

MEASUREMENT FOUNDATION

ZCT 777

Standard Deviation(Sdev.)

The sample standard deviation is a statistic that measures how “spread out” the sample is around the sample mean.

Standard deviation calculates in the following way:

Variance S2= ∑(x- -)2 /(n-1)

Auto power off (menu item 2.7)

You can disable Auto-power-off via MENU system.

Limit Function (menu item 3)

Limits can be entered during and after a series of measurements. There is practical use for limits. Any reading which falls outside the set tolerance limits will be registered by a warning indication: H: reading above HI limit L: reading below LO limit Please set the limit values using MENU system for reading above (menu item 3.1.1) and for reading below (menu item

3.1.1). Use buttons ▲/▼.

Delete Functions (menu item 4)

In MENU system, you can nd following function: Delete current data: If you nd the last measuring reading is wrong, you can delete it via this function (menu item 4.1). At

the same time, the statistics will be updated. Delete all data: You can delete all data and statistics of the Current Work Mode (menu item 4.2).

Delete Group data: this function includes “Delete all data” function (menu item 4.3).

Total-Reset

A total reset erases data from all memories. This includes all sets of readings of all work modes plus their associated statistics, calibration values and tolerance limits. a) Switch off gauge. b) Press ZERO+ simultaneously.

c) The LC display “sure to reset”, Press red-bar button for YES, or blue-bar button for NO.

d) The gauge will restart automatically.

e) If you want to cancel “NO”from the reset, press blue button.

Measurement view (menu item 5)

Via “Measurement view” in MENU, you can look through all measurement readings for current group.

Calibration (menu item 6)

There are three different methods available for calibration:

“Zero-point calibration”: recommended if measuring errors up to +-(3% of reading plus constant error of probe) are

1. permitted. (Example for constant of probe be error: Fe 1um; no-Fe 1.5um)

“One-point calibration” (calibrating using a calibration foil): recommended if readings to be expected will be close

2. to the calibration value and if the permitted error of probe will be max. +-(1%...3% of reading plus constant probe error)

“Two-point calibration” (using a set of two calibration foils):

A ) Recommended for measurements on rough surfaces. B) Recommended for precise measurements on smooth surface if the thickness to be expected lies between that of the two calibration foils.
